Fabric interface configuration management

1/0/2
NOTE
After you repair any segmented or disabled ISL ports, toggle the fabric ISL in order to propagate the
changes.
NOTE
A node on an operating ISL interface not only brings down the physical link but also its
FSPF adjacency. The main difference between a node and disabling fabric ISL is that
the link stays up after disabling fabric ISL, while the link stays down after a shutdown.
NOTE
Upon fabric reconvergence due to topology change involving the ECMP fabric-ISL path, there may be
sub-second flooding of known unicast traffic.
NOTE
Using an XGIG analyzer between switches in a Brocade VCS Fabric may cause a signal detection
timeout, causing the fabric ISL link to fail.
Enabling a fabric trunk
Fabric trunking is enabled on fabric ISLs by default. If trunking has been disabled, you can
re-enable it with the following steps.
1. Issue the RPC to configure the node in the
urn:brocade.com:mgmt:brocade-interface namespace.
2. Under the node, include the , ,
, or node element.
3. Under the , , , or
node element, include the leaf element and specify the
name of the interface on which you want to enable fabric trunking. Specify the name in
[rbridge-id/]slot/port format.
