The commands listed in Table 25-11 are BPX specific.
Compatibility Between Cards in Virtual Trunks
Virtual trunking is supported on the BNI and BXM cards in the BPX, and on the UXM card in the IGX.
Note that firmware levels on these cards must be current.
While virtual trunking is supported on the BPX and IGX, BNI virtual trunks are not compatible with
BXM/UXM virtual trunks because the BXM and UXM cards both use the standard UNI and NNI cell
header formats across the virtual trunks (instead of the Strata-UNI cell format used on BNI virtual
trunks).
To use virtual trunking on a BXM or a UXM card, Release 9.2 software is required, and Release 9.2
BXM and UXM firmware. No hardware upgrade is required. The new firmware is backward
compatible.
