stvid	Spanning Tree VLAN ID (0 - 4095). Values: An integer in the range 0 to 4095. The value 0 means no VLAN tag. Initial value is 4095 This parameter not valid in NOTAG mode. This parameter applies only to the LNW70/LNW170.
vmode	VCG Monitoring Mode may have one of the following values: AUTO - port automatically goes in-service (IS) when a valid input is received. NMON (not monitored)
vss	VCG Spanning Tree Status. Values are as follows: Enable (initial value): Enables VCG port for spanning tree Disable: Disables VCG port for spanning tree When enabling the VCG port for Spanning Tree, the retrieved spanning tree status could be "blocked", "discarded", or some other status value depending on the state of the spanning tree. This parameter is not valid in NOTAG mode. This parameter does not apply to the LNW63, LNW64, LNW71, LNW74, LNW87, or LNW78 ports.
dftpri	Port Default Priority This is the (default) provisioned Class of Service (CoS). This is the CoS as it is encoded in the first 2 bits in the user_priority field of the VLAN tag. For the LNW70/LNW170, this parameter is used to provision the default CoS. It only pertains to ports with porttype BOUNDARY. The allowed values for dftpri are integers in the range 0 to 3 and NA. Value 3 is the highest priority and 0 (initial value) the lowest. For the LNW78, this parameter is used to provision the default CoS. It has effect only if trafmgmtmd is PORT or COSPORT. The allowed values are integers in the range 1 to 3. Value 3 is the highest priority (Class A) and 1 (Class C) the lowest. Initial value is 1. When trafmgmtmd is PORT, changing dftpri is only possible when all QoS services created on this port (using ENT-ERATE) have been deleted (using DLT-ERATE). Traffic will not be interrupted, but will be unmetered until a new QoS service has been created for the (new) dftpri. This parameter applies only to the LNW70/LNW170 and LNW78 circuit packs.
addporttag	Port Tag identifiers, from the Configuration → Data → Create Port Tag command, to be added. Composite list of port tag identifiers to be added. Values are an ampersand (&) (TL1 command) or comma (,) (WaveStar^® CIT) separated list of port tag identifiers. Port tag identifiers are integers in the range from 1 to 4093. The addporttag value cannot be the same as a value provisioned for the dftporttag parameter. Except for the LNW70/LNW170 and LNW78 circuit packs, this parameter is valid only in TRANS (transparent) mode and may not be a value in another Virtual Switch. For the LNW70/LNW170 and LNW78, the addporttag value may be provisioned in another virtual switch. For the LNW70/LNW170 and LNW78 circuit packs, this parameter is valid when the VLAN Tagging Mode (vlantagmd) is set to SWITCHED and the port belongs to a virtual switch with tagmd set to TRANS. This parameter does not apply to the LNW63, LNW64, LNW71, LNW74, LNW87, or LNW78 ports.
delporttag	List of Port Tag identifiers to be deleted. Values: An integer in the range 1 to 4,093. The initial status of this list is empty. The addporttag or delporttag parameter can be provisioned by this command but not both. They must be provisioned by separate command instances. This parameter is valid when vlantagmd is set to TRANS or when vlantagmd is set to SWITCHED and the port belongs to a virtual switch with tagmd set to TRANS. This parameter does not apply to the LNW63, LNW64, LNW71, LNW74, LNW87 or LNW78 ports.
dftporttag	Default Port Tag (Default Vlan ID) from the Configuration → Data → Create Port Tag command is an integer in the range "1–4093", or "0". A "0" means that the user does not want a default value to be set. Except for the LNW70/LNW170 and LNW78 circuit packs, this parameter is valid only in TRANS (transparent) mode and may not be a value in another Virtual Switch. For the LNW70/LNW170 and LNW78, the dftporttag value may be provisioned in another virtual switch. For the LNW70/LNW170 and LNW78 circuit packs, this parameter is valid when the VLAN Tagging Mode (vlantagmd) is set to SWITCHED and the port belongs to a virtual switch with tagmd set to TRANS. The dftporttag value cannot be on or be provisioned in the active composite list of Port Tag identifiers added by the addporttag. A default porttag cannot be entered if porttype is INTERIOR or if portrole is NETWORK. This parameter does not apply to the LNW63, LNW64, LNW71, LNW74 or LNW87 ports.
tagfilter	Tag Filter. This parameter is used to enable/disable VLAN/Port Tag filtering and may be one of the following: ENABLE (initial value): allows only provisioned VLANs/port tags on a port. DISABLE: allows all VLANs/port tags on a port. Tag Filter does not prevent creating, modifying, or deleting VLANs. This parameter does not apply to the LNW63, LNW64, LNW71, LNW74, LNW87 or LNW78 ports.
vpm	VCG PM Enable. This parameter controls when performance monitoring is enabled for the specified VCG. Use the Performance → Prov PM Settings command from the System View menu to set this performance monitoring parameter to one of the following values: Enable (initial value) Disable
psctl	Pause Control. Pause Control may have one of the following values: TRANSPARENT (full rate end-to-end flow control) Enable Pause control pass-through Disable Pause control generation LOCAL (initial value) (sub-rate local flow control) Disable Pause control pass-through Enable Pause control generation NONE Disable Pause control pass-through Disable Pause control generation This parameter does not apply to the LNW63, LNW64, LNW70/LNW170, LNW71, LNW87 or LNW74 Ethernet ports.
ethertype	Ethernet Type (in Hex.) field (TPID). Used to interwork with other vendors' equipment using stacked VLAN. Values: A string in the range "0601" to "FFFF". The default value is "FFFF" (hexadecimal). Except for the LNW70/LNW170, this parameter is valid only when vlantagmd is set to TRANS (transparent) mode. For the LNW70/LNW170 circuit pack, this parameter is valid when the LNW70/LNW170 VLAN Tagging Mode (vlantagmd) is set to SWITCHED and the port belongs to a virtual switch with tagmd set to TRANS. When the Ethertype parameter is provisioned to any value other than FFFF or 8100, the PIR rate limiting feature on the LNW66/LNW67/LNW68 is not effective in transparent mode.
tcamd	TCA Mode Enable. This parameter specifies whether performance monitoring Threshold Crossing Alert reporting is enabled or disabled for the port, addressed by the aid. Enabled Disabled (initial value) TCA reporting will not begin until tcamd is enabled and port monitoring mode is enabled (vpm = ENABLE), and the port is in service (vmode = IS). This parameter does not apply to the LNW78 ports.
mtu_size	The MTU size parameter specifies the Maximum Transmission Unit (MTU) size (in bytes) supported on the port. The MTU size is the size of the payload in the Ethernet frame, excluding Source and Destination Address, Type and CRC field, but including all VLAN tags. Any VLAN on the frames or added to the frame by the system will effectively reduce the maximum MTU size. This parameter applies only to the LNW70/LNW170 and LNW78 circuit packs. The valid value is an integer in the range 46 to 10222 (default is 1508).
emsdt	Exceeded MTU Size Drop Threshold. This parameter specifies the point at which an alarm is generated when the ratio (Exceeded MTU size drop count / Total frame received count) surpasses the set threshold. Value: an integer in the range 0 (feature disabled) to 1000 (100%), in steps of 1 (0.1%). The initial value is 0 (feature is disabled). “Feature disabled” indicates that the “exceeded MTU size drop” (emsd) alarm is NOT generated when the threshold is surpassed. This parameter applies to the LNW70/LNW170 circuit packs.
gfp_fcs	GFP Frame Check Sequence. This parameter controls the handling of the GFP FCS field for the specified VCG. The valid values are ENABLE DISABLE Parameter is valid only for LNW63, LNW64, LNW70/LNW170, LNW74, LNW87 and LNW78 circuit packs. When interworking with equipment that does NOT support GFP FCS, the parameter should be set to DISABLE. On the LNW63 and LNW74 circuit packs, this parameter only controls the transmit of the GFP FCS. The GFP FCS on receipt will be handled depending on the presence or not of the GFP FCS field as indicated by the received PFI bit. If GFP FCS is present it will always be checked. On the LNW64, LNW70/LNW170, LNW87 and LNW78 circuit packs, this parameter controls both the transmit and receive of the GFP FCS. On receipt, the GFP FCS field will be checked for (and should be present) when gfp_fcs is ENABLED, and the GFP FCS will NOT be checked for (and should NOT be present) when gfp_fcs is DISABLED.
bcratelimit	Broadcast and Multicast rate limit. This is the data rate limit, in Mbps, for incoming packets whose destination address is the broadcast address (FF-FF-FF-FF-FF-FF). It also includes all multicast addresses (XO-XX-XX-XX-XX-XX where “O” is an odd hexadecimal digit) including Bridge Filtered MAC group addresses used by PAUSE frames, BPDUs, Link Aggregation, etc. It also limits incoming packets whose destination address has not been learned (and therefore are broadcasted). This limit applies to the aggregate of all traffic at a port. While broadcast rate limiting is always enabled at a port, setting the limit greater than or equal to the port speed has the effect of no rate limiting. Valid value is an integer value between 0 and 1000000 representing Kbps. A value of 0 (initial value) disables broadcast rate limiting. This parameter is valid for LNW70/LNW170 VCGs and LNW78 Ethernet over SONET (EoS) VCGs only if the selected port is part of a virtual switch and the VLAN Tagging Mode of the circuit pack is set to Switched.
lcasmd	LCAS Mode. This parameter controls whether LCAS (Link Capacity Adjustment Scheme) is enabled for the specified VCG. When enabled, the LCAS protocol allows for hitless changes to the provisioned size of the VCG. Values for LCAS Mode: ENABLE (initial value) DISABLE The lcasmd parameter applies only to the LNW63, LNW64, LNW70/LNW170, LNW74, LNW87 and LNW78 circuit packs
htmr	Hold-Off Timer (in milliseconds). This parameter specifies the delay between when a tributary is detected faulty and when it is automatically removed from the VCG. It allows underlying protection, if any, to react first for removal of failed links. It applies to all tributaries in the specified VCG. Values: 0 to 10,000 ms (10 sec), in 100 millisecond steps. Initial value is 200ms. 99,999 ms (represents infinity). If the vlantagmd is changed to SWITCHED on the LNW70/LNW170, htmr values for all VCGs will be set to the initial value of 99,999. This parameter applies only to the LNW63, LNW64, LNW70/LNW170, LNW74, LNW87 and LNW78 Ethernet ports and is in effect only if LCAS Mode (lcasmd) is set to ENABLE.
wtr	Wait-to-Restore (in seconds). This parameter specifies the delay between when a tributary, previously removed from the VCG because of fault, is detected to be normal and when it is automatically returned to the VCG. It applies to all tributaries in the specified VCG. Values are from 0 to 3600 seconds in 1 second steps (initial value = 5). This parameter applies only to the LNW63, LNW64, LNW70/LNW170, LNW74, LNW87 and LNW78 Ethernet ports and is in effect only if LCAS Mode (lcasmd) is set to ENABLE.
vcat	Virtual Concatenation Mode. Specifies whether H4 is inserted/monitored for the specified VCG. It has effect only when a single trib, not VT, is cross-connected to the VCG, to allow interworking with non-VCAT equipment. Valid values are ENABLE (default) DISABLE The vcat parameter applies only to the LNW63, LNW64, LNW70/LNW170, LNW74, LNW87 and LNW78 circuit packs.
porttype	Port Type. Specifies whether the port is at the boundary of the DiffServ domain or is a port interior to the DiffServ domain. Used in provisioning QoS services. Values are: BOUNDARY (only allowed value for the LNW78). INTERIOR (initial value for the LNW70/LNW170). This parameter applies only to the LNW70/LNW170 and LNW78 circuit packs, when the port is part of a virtual switch, and vlantagmd is SWITCHED.
portrole	Port Role. Port Role controls how tags are added/removed/processed. In typical applications, “boundary” ports are “customer” ports and “interior” ports are “network” ports. Port role has the following values: Valid values are Customer (Initial and only allowed value for the LNW78). Network (Initial value for LNW70/LNW170. Port must not have a default VLAN ID or porttag). This parameter applies only to the LNW70/LNW170 and LNW78 circuit pack ports, when the port is part of a virtual switch, and vlantagmd is SWITCHED.
trafmgmtmd	Traffic Management Mode. Specifies how the packets will be divided into traffic flows and the services that can be provided at the port. Values are: NOTC: This mode is valid for Boundary ports (see porttype) only in TRANS and 802.1Q tagmd (see ENT-VRTSW). It is also valid for Private Line ports. There is no traffic conditioning of packets that are received at the port. This mode emulates behavior of the LNW66/67/68. User_priority values 0, 1, 2 and 3 are mapped to CoS 0 and user_priority values 4, 5, 6 and 7 are mapped to CoS 3. The p-bits of the user frames are not changed. This mode is supported for the LNW70/LNW170. Initial value for the LNW70/LNW170. PORT: This mode is valid for Boundary ports only (see porttype) in TRANS and 802.1Q tagmd (see ENT-VRTSW). All traffic received at the port is processed by a single traffic conditioner. The user_priority bits are remarked with the dftpri and the drop precedence determined from the traffic conditioner according to the provisioned mapping (see ED-ERATE). This mode is supported for the LNW70/LNW170 and LNW78. Initial value for the LNW78. COSPORT: This mode is valid for BOUNDARY ports only (see porttype) in 802.1q tagmd (LNW70/LNW170, LNW78) and TRANS tagmd (LNW70/LNW170 only) (see ENT-VRTSW). All traffic received at the port that is tagged with the same 802.1p user_priority is processed by a single traffic conditioner for the CoS that is provisioned for that user_priority (see userpri2cos in ED-ERATE). There can be one service for each provisioned CoS at the port. For 802.1q tagmd, the user_priority bits are remarked with the original CoS and the drop precedence, which was determined from the traffic conditioner, according to the provisioned user_priority mapping (see ED-ERATE). For TRANS tagmd, the CoS level for untagged traffic is set to the default priority (dftpri) or 0 if dftpri is NA. The added stacked/outermost TAG user_priority bits are marked with the CoS and the drop precedence, which was determined from the traffic conditioner, according to the customer user_priority mapping (see ED-ERATE). But the customer VLAN TAG user_priority bits are untouched and preserved.
trafmgmtmd (cont.)	TAGPORT: This mode is valid for Boundary ports only (see porttype) in 802.1Q tagmd (see ENT-VRTSW). All traffic received at the port that is tagged with the same VLANid is processed by a single traffic conditioner. The user_priority bits are remarked with the dftpri2cos (see ED-ERATE) and the drop precedence determined from the traffic conditioner according to the provisioned mapping (see ED-ERATE). This mode is supported for the LNW70/LNW170. COSTAGPORT: This mode is valid for BOUNDARY ports only (see porttype) in 802.1Q tagmd (see ENT-VRTSW). All traffic received at the port that is tagged with the same VLANid and the same CoS is processed by a single traffic conditioner for the VLANid and that CoS. There can be one service for each provisioned CoS (up to 4) on each provisioned VLANid at the port. The user_priority bits are remarked with the original CoS and the drop precedence, which was determined from the traffic conditioner, according to the provisioned user_priority mapping (see ED-ERATE). This mode is supported for the LNW70/LNW170.
hlayercos	Higher layer Class of Service (CoS). This determines whether the packets will be classified by a higher layer protocol such as DiffServ Code Point (DSCP) in the IP header. Higher layer classification is only supported when trafmgmtmd in set to PORT. Values: NONE: Higher layer not used for classification (initial value). DSCP: Use the DSCP bits in the IP header for classification. This parameter applies only to an LNW70/LNW170 circuit pack port.

This parameter applies only to an LNW70/LNW170 circuit pack port that is part of a virtual switch when the circuit pack VLAN Tagging Mode (vlantagmd) is set to SWITCHED.
qsz	Total Queue Size. Specifies the total queue size for the port, including the EF and AF queues as well as the management queues. Beginning in Release 9.1, VCGs on LNW70/170 (in private line mode) support the following values for total queue size. NA (default) Not Applicable. The ingress queue size is automatically set as a function of mtu_size and fcmd, consistent with releases prior to Release 9.1 128 The ingress queue size is 128 Kbytes. This value is supported for FE ports only. 512 The ingress queue size is 512 Kbytes. This value is supported for GE ports only. VCGs on the LNW70/LNW170 support the queue size parameter. If the vcg is part of a virtual switch and the VLAN Tagging Mode (vlantagmd) is set to SWITCHED, valid value is an integer between 0 and 256 Kbytes (default is 256 Kbytes). The value cannot be greater than the maximum supported frame size. Refer to the MTU Size parameter.
