7210 SAS

7210 SAS-D support

The 7210 SAS-D is an intelligent Ethernet edge-demarcation device that extends enhanced Carrier Ethernet VPN service delivery to the CE. The license for a 7210 SAS-D is based on the chassis type.

Note: The NFM-P supports only access mode for 7210 SAS-D 6F 4T ETR ports.

7210 SAS-Dxp support

The 7210 SAS-Dxp is an intelligent Ethernet demarcation switch that extends enhanced Carrier Ethernet VPN service delivery to the CE and can operate in access-uplink mode. The 7210 SAS-Dxp router uplinks to the network using Layer 2 Ethernet VLAN switching (without IP/MPLS).

The 7210 SAS-Dxp 16 and 24 port variants supports PoE connections. See To configure PoE ports on a 7210 SAS for more information.

7210 SAS-E support

The 7210 SAS-E is a Carrier Ethernet CE device that is typically owned and managed by a customer. Using software based on the 7750 SR OS and managed by the NFM-P, the 7210 SAS-E extends Carrier Ethernet VPN services to the CE. The 7210 SAS-E can also be deployed as an aggregation device for smaller sites.

7210 SAS-E daughter cards

The 7210 SAS-E supports an integrated 2 × 12-Gig IOM card on a single chassis. The equipment navigation tree displays a card slot with one daughter card that contains 12 × 100/1000 Ethernet SFP ports and 12 × 10/100/1000 Ethernet ports.

7210 SAS-K support

The 7210 SAS-K is an intelligent Gigabit Ethernet switch that provides aggregation and demarcation for services managed to the customer edge.

7210 SAS-M support

The 7210 SAS-M is a CE device that provides MPLS-enabled metropolitan and WAN Carrier Ethernet service delivery, Ethernet-based mobile backhaul, and residential service access. In access uplink mode, the 7210 SAS-M provides Ethernet aggregation and demarcation for services managed to the customer edge.

The chassis mode is changed using a CLI to modify the device BOF. A reboot of the device is required for the change to take effect. When you change the chassis mode of a 7210 SAS-M, you must un-manage and re-manage the NE. The NFM-P displays the chassis mode as the State parameter, in the Uplink Mode panel on the General tab of the shelf properties form for the device.

See the NE documentation for more information.

7210 SAS-Mxp support

The 7210 SAS-Mxp is an IP/MPLS-enabled 1GigE and 10GigE access and aggregation device that can operate in two modes:.

Note: The 7210 SAS-Mxp is not a variant of the 7210 SAS-M.

The 7210 SAS-Mxp ETR supports PoE connections on ports 23 and 24. See To configure PoE ports on a 7210 SAS for more information.

7210 SAS-R support

The 7210 SAS-R Ethernet switch is suitable for aggregation in access Ethernet networks, and is also capable of MPLS and MPLS-TP service transport. The 7210 SAS-R has multiple IMM card slots and dual redundant CPM/SF slots.

IMM card support

First-generation IMM cards (also called KT1 or imm-sas-r) are supported on the 7210 SAS-R6. Access, network, and hybrid port modes are supported. For 1-Gig ports, the port speed is variable.

The NFM-P supports a third IMM card family, called TR3 (or imm-sas-r-c) on supporting releases of the 7210 SAS-R6 and 7210 SAS-R12. Ports on TR3 cards are supported in network mode only. The port speed is not configurable.

For the 22 CSFP card, the NFM-P displays 22 ports on the navigation tree, even when SFP transceivers are used.

Automatic provisioning of IMM cards

The NFM-P automatically provisions and configures IMM cards on the 7210 SAS-R. Auto-provision occurs for unprovisioned cards during node discovery, or when the NFM-P receives notification that a card is inserted in a managed 7210 SAS-R.

The NFM-P auto-provisions cards that match the operational IMM family type displayed on the shelf properties form for the device. See To configure the IMM card type on a 7210 SAS-R. The 7210 SAS-R6 supports KT1, KT2, and TR3 IMM cards. If no IMM family type is configured, then by default only KT1 cards are auto-provisioned. The 7210 SAS-R12 supports KT2 and TR3 IMM cards. If no IMM family type is configured, then by default only KT2 cards are auto-provisioned.

7210 SAS-S support

The 7210 SAS-S is a 1-Gig and 10-Gig Ethernet switch that can operate in two modes:

The 7210 SAS-S is similar to the 7210 SAS-Sx, but has a reduced set of hardware features.

7210 SAS-S/Sx virtual chassis support

The 7210 SAS includes support for virtual chassis/stacking with 7210 SAS-Sx/S 1/10GE platforms for EPIPE, VPLS, RVPLS services with IP/MPLS. To increase port density at an access aggregation site, virtual stack of nodes can be configured using the stacking ports available on the rear of the chassis. To simplify the operations and management, the stack of nodes is presented as a virtual chassis, with a single IP address to use for managing the platform.

With stacking, operators have an option to add ports at an access aggregation site as connectivity requirements increase, while maintaining the operational simplicity of managing a single node.

7210 SAS-S/Sx VC in the NFM-P equipment tree

When the 7210 SAS-S/Sx VC is displayed in the NFM-P equipment tree, the IMM functionality of the CPM-IMM cards is shown as Card Slot- n, based on the configuration specified while bringing up the node. The CPM functionality of the CPM-IMM cards is shown as Card Slot- A and Card Slot- B.

Ethernet IMMs can be provisioned in any of the six IMM slots on the 7210 SAS-S/Sx VC, and can be managed by either of the CPM-IMM cards, depending on configuration and the operational state of the CPM-IMMs. If a CPM-IMM is removed or goes down, control of the MDAs is taken over by the other CPM-IMM to provide redundancy.

The power supplies and fan tray parameters are displayed under navigation tree equipment view for all the stack members. For each power supply and fan tray, the corresponding card number is listed. Power supply 1 on card 1 is displayed as 1/1 under power supplies.

7210 SAS-Sx support

The 7210 SAS-Sx is an Ethernet switch that can operate in two modes:

The 7210 SAS-Sx is similar to the 7210 SAS-S, but has an enhanced set of hardware features. NFM-P support for the 7210 SAS-Sx and 7210 SAS-S is not identical.

7210 SAS-T support

The 7210 SAS-T is an Ethernet access device that provides MPLS-enabled metropolitan and WAN Carrier Ethernet service delivery, Ethernet-based mobile backhaul, and residential service access. In access uplink mode, the 7210 SAS-T provides Ethernet aggregation and demarcation for services managed to the customer edge.

The NFM-P supports two chassis modes for the 7210 SAS-T:

The chassis mode is changed using a CLI to modify the device BOF. A reboot of the device is required for the change to take effect. When you change the chassis mode of a 7210 SAS-T, you must un-manage and re-manage the NE. The NFM-P displays the chassis mode as the State parameter, in the Uplink Mode panel on the General tab of the shelf properties form for the device.

See the NE documentation for more information.

The 7210 SAS-T ETR supports PoE connections on ports 19, 20, 21, and 22. See To configure PoE ports on a 7210 SAS for more information.

7210 SAS-X support

The 7210 SAS-X is an MPLS-enabled Ethernet aggregation device for small and medium-sized networks that provides business, mobile backhaul, and residential services. The 7210 SAS-X is similar to the 7210 SAS-M, but has 10Gb/s uplink ports, enhanced traffic management, greater scalability, and hierarchical QoS functions.

System resource profile

The NFM-P supports system resource allocation on 7210 SAS devices using the system resource profile. You can configure system resources to suit your network requirements by assigning more resources to functions that are used extensively, and fewer resources to functions that are used less. Unused functions can be disabled, and their resources made available for other functions. The functional areas that are configurable vary depending on the chassis type.

System resources are allocated in units called chunks. The number of chunks and the chunk size vary by device chassis.

Resources are allocated by assigning a value from the applicable range. A value of zero disables the function. The sum of resources allocated must not exceed the total available resources for the system. If you assign more than the allocated number of chunks, functions are disabled.

For SAP ACL and SAP QoS functions, configuring system resources is accomplished in two steps. First, divide overall system resources among the main functional areas: SAP ingress internal ACL, SAP egress internal ACL, and SAP ingress QoS. Second, allocate the resources specified for each functional area to the criteria within that function, such as MAC, IPv4, and 64 or 128-bit IPv4/v6. The total number of chunks assigned to the criteria must not exceed the number of chunks allocated to the function. When you specify a value of MAX, the system allocates resources as required on a first-come, first-served basis, up to the available limit.

For all 7210 SAS chassis types except the 7210 SAS-R and 7210 SAS-VC, system resource profile allocations are configured globally on the NE properties form; see To configure the global system resource profile on a 7210 SAS or 7250 IXR .

For the 7210 SAS-R and 7210 SAS-VC, some resource allocations are configured globally on the NE properties form, and some are configured using system resource profile policies assigned to card slots on the device; see To configure a system resource profile policy for the 7210 SAS-R/T/Mxp, 7210 SAS-S/Sx, or 7210 SAS-S/Sx VC and To select system resource profile policies for the 7210 SAS-R or 7210 SAS-S/Sx VC .

See the 7210 SAS documentation for more information about system resource allocation.
