Rbridge-id RBridge-id of the switch. Valid values range from 1 through 239.

#ISLs Number of ISLs connected.

Src Index Source index of the local RBridge.

“local-rbridge-id/slot/port”. If the ISL is not up, then “?/?/?” displays for a

Te interface and “-/-/-” displays for an Fi interface.

segmented and the NBR rbridge details are unavailable, “?” displays in this

field.

format “nbr-rbridge-id/slot/port”. If the ISL is not completely up, this field

will be displayed as “?/?/?”.

RBridge.

The show fabric family of commands displays neighbor and local port information when connected

to a down-level RBridge.

For segmented links, “(segmented - incompatible)” is displayed to indicate that the ISL is

segmented. The Nbr Index, Nbr Interface, and Nbr-WWN files show question marks if the

information is not known.
