Configuring Sfm5-12E Fabric Speed; Fabric-Speed-A; Fabric-Speed-B - Alcatel-Lucent 7750 Configuration Manual

Configuring SFM5-12e Fabric Speed

With the introduction of SFM5-12e and the mini-SFM5-12e, a new tools command (set-fabric-
speed) was added to set the fabric operating speed. (tools command does not apply to SFM4-12e
fabric-speed-a). 7750 SR-7 and 7750 SR-12 support fabric-speed-b.

fabric-speed-a

The 7750 SR-12e chassis defaults to the fabric-speed-a parameter when initially deployed with
SFM5-12e. The fabric-speed-a parameter operates at 200GB per slot which permits a mixture of
FP2/FP3 based cards to co-exist.

fabric-speed-b

The fabric-speed-b parameter enables the 7750 SR-12e to operate at up to 400 Gb/s, for which all
cards in the 7750 SR-12e are required to be T3 based (FP3 IMM and/or IOM3-XP-C). The system
will not support any FP2 based cards when the chassis is set to fabric-speed-b.
