Line Card Installation

Side-by-side Redundancy for the XGLC

The XGLC is a full-height card that requires both top and bottom line card slots for a single 10-Gigabit port.
To achieve one-to-one line card redundancy, you must install two XGLCs in adjacent slots. Otherwise, you
configure port and card redundancy for the XGLCs in the same way as other line cards. There are no restrictions
that prevent the side-to-side 1:1 XGLC redundant arrangement from functioning with other Ethernet line card
types.
An active packet processing card must always be installed behind an XGLC. Monitoring functions occur in
a distributed fashion. Select the XGLCs that act as a redundant pair via the CLI. Configure the redundant pairs
prior to configuring the interface bindings so that proper parallel physical and logical port configurations are
established. The card redundancy and monitoring begins as soon as the packet processing card in front is
active.

Requirement Summary

There must be a direct connection to a packet processing card behind each side-by-side redundant XGLC pair.
Configure the XGLC Ethernet line cards in a chassis as redundant pairs with cards in the following adjacent
slots:
• 17 – 18
• 19 – 20
• 21 – 22
• 23 – 26 (SPIOs 24 and 25 are skipped in this line card redundancy model)
• 27 – 28
• 29 – 30
• 31 – 32

CLI Commands for XGLC Redundancy

Side-by-side 1:1 redundancy only operates on top line card slot numbers: cards 17 through 23 and 26 through
32. Make sure that both packet processing cards in front of the line cards are of the same type, configured as
a redundant pair, and active.The CLI configuration to support this redundancy mode is specified at the card
level as follows:
[local]asr5000#
[local]asr5000(config)#
[local]asr5000(config-card-17)#
The packet processing cards behind a pair of redundant XGLCs must always be in Active mode.
Use only the top line card slot numbers to configure XGLC 1:1 redundancy.
