member-link pos
Associates a POS interface into a composite-link.
Syntax: [no] member-link pos bay/slot/port
bay/slot/port
Identifies a specific interface on the Avici router. Valid values are as follows:
bay: Identifier for this bay. Valid values are 1 and 2.
slot: Slot number where the module is installed. Valid values are 1 - 40.port:
Description: A composite link is a number of individual POS interfaces configured to collectively operate as a composite. Member links run over OC-3c, OC-12c, OC-48c and OC-192c POS interfaces. Up to 64 composite links can be configured per Avici router.
Up to 64 member links can be associated into a composite link.
NOTE Because OC-192c interfaces consist of 4 internal OC-48c interfaces, composite links composed of OC-192c member links may have only up to 16 member links per composite link.
Individual member-links can be associated with only one composite-link.
The speed of member links in a composite link must have no more than a 4:1 ratio. If an existing composite link consists of OC-3c interfaces, you can only add OC-3c or OC-12c interfaces to the composite link. If an existing composite link consists of OC-12c and OC-48c interfaces, you can not add an OC-3c interface to that composite link.
NOTE OC-192c interfaces consist of 4 internal OC-48c interfaces that are associated into the OC-192c composite link, and operate as a single interface. Because the underlying interfaces are OC-48c, an OC-192c interface can be associated into the same composite link as an OC-12c interface and still preserve the required 4:1 ratio for line speed.
The individual interfaces on a routing module can be associated with different composite links. For example, the 2 interfaces of a 2xOC-48c routing module can be associated with two different composite links, or the same composite link.
Up to 4 interfaces on each routing module can be associated with a composite link.
Use the interface composite-link command to create a composite link and change the command mode to add individual member-links.
Use the ip address command to assign an IP address and mask to the composite link. The member links of the composite link inherit this IP address.
Use the ip router isis command to enable IS-IS routing on the link and to activate the OSICP.
Use the member-link pos command to add member-links to the composite link.
Use the no member-link pos command to delete member links from a composite link.
Factory Default: No composite links or member-links defined.
Command Mode: Interface configuration.
Example 1: In the following example:
- The interface composite-link command defines a composite link named Boston2LA and changes the command mode to interface configuration mode.
- The ip address command assigns an address and mask to the composite link. This address is inherited by all the member links associated with the composite link.
- The peer default ip address command assigns an address to the remote interface. This address is inherited by all members of the composite link.
- The member-link-pos commands associate two POS interfaces with the composite link.
- The ip router isis enables IS-IS routing and OSICP.
- The show ip interface command displays the association.
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#interface composite-link Boston2LA
router(config-if)#ip address 10.5.12.134 255.0.0.0
router(config-if)#peer default ip address 10.5.18.123
router(config-if)#member-link-pos 1/1/1
router(config-if)#member-link-pos 1/1/2
router(config-if)#no shutdown
router(config-if)#ip router isis 46
router#exit
router#show ip interface
POS 1/1/1 is up, line protocol is up
Member of composite-link Boston2LA
MTU 4470 bytes, BW 155 Mbps
POS 1/1/2 is up, line protocol is up
Member of composite-link Boston2LA
MTU 4470 bytes, BW 155 Mbps

Example 2: In the following example, the no member-link pos command deletes the association between the composite-link and POS interface 1/1/1, and the show ip interface brief command displays the new setting:
NOTE Member-links inherit Layer-3 attributes from their composite link. When the association between member link and composite link is deleted, the member link has no assigned ip address and mask or peer default ip address, and the MTU is reset to the default (4470 for POS links).
router(config)#interface composite-link Boston2LA
router(config-if)#no member-link-pos 1/1/1
router(config-if)#end
router#show ip interface brief pos 1/1/1
Interface IP Address Status Line Protocol
POS 1/1/1 not assigned up up
