Verifying Line Card And Spio Port Redundancy Auto-Recovery; Configuring Asr 5000 Link Aggregation - Cisco ASR 5000 Administration Manual

Verifying Line Card and SPIO Port Redundancy Auto-Recovery

A preference cannot be configured in normal redundancy mode. Attempting to do so will produce an error

message from the CLI command.
Save the configuration as described in the Verifying and Saving Your Configuration chapter.
Verifying Line Card and SPIO Port Redundancy Auto-Recovery
Verify port information by entering the following command
show port info slot#/port#
slot# is the chassis slot number of the line card on which the physical port resides.
port# is the physical port on the line card.
The following shows a sample output of this command for port 1 on the LC in slot 17:

Configuring ASR 5000 Link Aggregation

A Link Aggregation Group (LAG) works by exchanging control packets via Link Aggregation Control Protocol
(LACP) over configured physical ports with peers to reach agreement on an aggregation of links as defined
in IEEE 802.3ad. The LAG sends and receives the control packets directly on physical ports attached to
different QGLCs (Quad Gigabit Line Cards) or XGLCs (10 Gigabit Line Cards).
Link aggregation (also called trunking or bonding) provides higher total bandwidth, auto-negotiation, and
recovery by combining parallel network links between devices as a single link. A large file is guaranteed to
be sent over one of the links, which removes the need to address out-of-order packets.
A LAG can be formed by configuring:
• Ports from the same QGLC
• Ports from top-bottom QGLCs with port redundancy
• Ports from side-by-side XGLCs
