Procedure 11-2: Provision VCG parameters

Overview

This procedure provides a list of provisionable parameters for virtual concatenation groups (VCGs) on VLNC35 Fast Ethernet and VLNC50/52/55 SONET/SDH Transport circuit packs.

Privilege level

You must login as either a Privileged or General user to complete this procedure.

Before you begin

Prior to performing this procedure, refer to Before you begin and Required equipment in this chapter and you must have complete work instructions for this procedure that detail:

The network configuration and the terminating Ethernet nodes.
The values to be set for each parameter.

Steps

Use this procedure as a reference for provisioning VCG parameters.

Use the ed-vcg TL1 command or select Configuration → Equipment from the System View menu for the majority of parameters. Expand the details for the circuit pack, select (highlight) the VCG port, then click Select.

Result:

Exceptions to provisioning parameters from the Configuration → Equipment command will be noted in the resulting table.

Reference:

Appendix A, Provisionable parameters

Use the following table as reference to provision the necessary parameters from your work instructions.

Important!

Some of the parameters may have already been provisioned from earlier procedures for establishing service.

ED-VCG command parameters

The following table lists the provisionable parameters for the ed-vcg command:

Table 11-2: ED-VCG Command Provisionable Parameters

Parameter	Description
addporttag	The Add Port Tag parameter is composite list of port tag identifiers to be added. The values are an ampersand-separated list of Port Tag identifiers, where each Port Tag identifier is an integer in the range 1-4093. A tag identifier’s value cannot be on or be provisioned in any of the active composite lists of Port Tag identifiers per the addporttag on any of the up to 8 VCGs of the same VLNC50/52/55 circuit pack. A tag identifier’s value cannot be on or have previously been provisioned by the dftporttag parameter in any of the up to 8 VCGs of the same VLNC50/52/55 circuit pack. A maximum of 32 VLANs may be provisioned across all 8 VCGs of the same VLNC50/52/55 circuit pack. This parameter only applies to the VLNC50/52/55 circuit pack when the VLAN tagging mode is provisioned as MUX and the Default Port Tag is provisioned as 0. This parameter does not apply to the VLNC35 circuit pack.
almlvl	The Incoming Signal Failure Alarm Level parameter sets the alarm level for an incoming signal failure, autonegotiation failure, and may have one of the following values: Critical (initial value). Major. Minor. Not Alarmed.
csfmd	The CSF Management Mode parameter controls whether a conversion between GFP CSF and Ethernet VSF is performed. Values include: ENABLE: The system supports conversions between GFP-CSF and ETH-VSF. DISABLE: The system does not support conversions between GFP-CSF and ETH-VSF (Initial Value). Changing csfmd from DISABLE to ENABLE is denied if the ED-EPORT rcf parameter is provisioned as DISABLE or if the ED-EPORT rcf_linkdown parameter is provisioned as ENABLE. This parameter only applies to the VLNC50/52/55 circuit pack when the VLAN tagging mode is provisioned as MUX and the Remote Client Fail parameter is Enabled. This parameter does not apply to the VLNC35 circuit pack.
delporttag	The Delete Port Tag parameter is composite list of port tag identifiers to be deleted. The values are an ampersand-separated list of Port Tag identifiers, where each Port Tag identifier is an integer in the range 1 to 4093. The initial status of this list is empty. This parameter only applies to the VLNC50/52/55 circuit pack when the VLAN tagging mode is provisioned as MUX. This parameter does not apply to the VLNC35 circuit pack.
dftporttag	The Default Port Tag parameter is an integer in the range 0 to 4093, or 0. A 0 means that the user does not want a default value to be set. The Default Port Tag value cannot be on or be provisioned in the active composite list of Port Tag identifiers added by the addporttag on any of the up to 8 VCGs of the same VLNC50/52/55 circuit pack. The Default Port Tag value must not be provisioned in another of the up to 8 VCGs of the same VLNC50/52/55 circuit pack. A maximum of 32 VLANs may be provisioned across all 8 VCGs of the same VLNC50/52/55 circuit pack. This parameter only applies to the VLNC50/52/55 circuit pack when the VLAN tagging mode is provisioned as MUX. This parameter does not apply to the VLNC35 circuit pack.
ethertype	The Ethernet Type field (TPID) parameter is used to interwork with other vendors’ equipment using stacked VLAN. The value is a hexadecimal string in the range from 0601 to FFFF. The default value is 8100 (hexadecimal). This parameter only applies to the VLNC50/52/55 circuit pack when the VLAN tagging mode is provisioned as MUX. This parameter does not apply to the VLNC35 circuit pack.
gfp_fcs	The GFP Frame Check Sequence parameter controls the handling of the GFP FCS field for the specified VCG. The valid values are ENABLE: When enabled, the GFP FCS is added to the outgoing frames. DISABLE: (initial value).
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). This parameter applies only if LCAS Mode (lcasmd) is set to ENABLE.
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 DISABLE (initial value) When the VCAT parameter is DISABLE, the LCAS mode parameter must be DISABLE.
tagfilter	The Tag Filter parameter is used to enable and disable VLAN Tag filtering. Values include: ENABLE (Tag filtering enabled) (Initial Value for VCGs 2 through 8) DISABLE (Tag filtering disabled) (Initial Value for VCG 1). Only one VCG may have its tagfilter value set to DISABLE. When the Tag Filter parameter has a value of DISABLE, the Default Port Tag value is set to 0 and the Add Port Tag list is emptied. This parameter only applies to the VLNC50/52/55 circuit pack when the VLAN tagging mode is provisioned as MUX. This parameter does not apply to the VLNC35 circuit pack.
tcamd	TCA Mode Enable. Select Performance → Prov PM Settings from the System View menu to Enable or Disable (initial value) performance monitoring Threshold Crossing Alert reporting for the specified port. 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).
vcat	The Virtual Concatenation Mode parameter controls whether VCAT overhead information is inserted/monitored for the specified VCG. It is valid only when a single tributary is cross-connected to the VCG. This allows interworking with non-VCAT equipment. The valid values are ENABLE (initial value). DISABLE. If an STS3c or VC4 rate cross-connection exists to the VCG on the VLNC35 circuit pack, the Virtual Concatenation Mode parameter cannot be provisioned ENABLE. When the VCAT parameter is DISABLE, the LCAS mode parameter must be DISABLE.
vmode	The VCG Monitoring Mode parameter may have one of the following values: AUTO - port automatically goes in-service (IS) when a valid input is received (initial value). NMON (not monitored).
vpm	VCG PM Enable. Select Performance → Prov PM Settings from the System View menu to set this performance monitoring parameter to one of the following values: Enable (initial value) Disable
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 if LCAS Mode (lcasmd) is set to ENABLE.
