Notes:
•
When activating cards, remember to keep at least one DPC/UDPC or DPC2/UDPC2 in standby mode
for redundancy.
•
Repeat for every other DPC/UDPC or DPC2/UDPC2 in the chassis that you wish to activate.
Save the configuration as described in the Verifying and Saving Your Configuration chapter.
Verifying Card Configurations
Verify that the configuration was successful. Enter the following command:
show card table
Any DPC/UDPC or DPC2/UDPC2 that you made active should now have an operational status of Active.
Enabling Automatic Reset of FSC Fabric
By default if an excessive number of discarded fabric egress packets occurred in the switch fabric, a manual
reset of the Fabric Storage Card(s) is required for fabric recovery.
You can optionally enable automatic resets of FSCs if an excessive number of discarded fabric egress packets
is detected.
A Global Configuration mode fabric fsc-auto-recover command enables or disables automatic FSC resets
upon detection of an excessive number of discarded fabric egress packets.
The following command sequence enables this feature:
configure
fabric fsc-auto-recovery { disable | enable } [ max-attempts [ number_attempts | unlimited ] ]
end
max-attempts [ number_attempts | unlimited ] specifies how many times StarOS will attempt to reset each
FSC as an integer from 1 to 99 or unlimited (will not stop until FSC is reset). The default setting is 1.
To enable this feature, you must first configure the Fabric Egress Drop Threshold via the Global
Configuration mode fabric egress drop-threshold command.

Configuring ASR 5500 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.
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.
