Displaying IPv4 IS-IS information
The Brocade device applies the interface-level metric to routes originated on the interface and also
when calculating routes. The Brocade device does not apply the metric to link-state information
that the Brocade device receives from one IS and floods to other ISs.
The default interface metric is 10. You can change the metric on an individual interface to a value
in one of the following ranges:
• 1 – 63 for the narrow metric style (the default metric style for IPv4 ISIS)
• 1 – 16777215 for the wide metric style (the default metric style for IPv4 ISIS)
NOTE
If the metric value you want to use is higher than 63 but you have not changed the metric style to
wide, change the metric style first, then set the metric. The IS-IS neighbors that will receive the
advertisements also must be enabled to receive wide metrics.
To change the IS-IS metric on an interface, use the following CLI method.
Brocade(config)# interface ethernet 2/8
Brocade(config-if-e1000-2/8)# isis metric 15
Syntax: [no] isis metric num [level-1 | level-2]
The num parameter specifies the metric. The range of values you can specify depends on the
metric style. You can specify 1 – 63 for the narrow metric style or 1 – 16777215 for the wide metric
style. The default in either case is 10.
The level-1 | level-2 parameter applies the change to only the level you specify. If you do not use
this parameter, the change applies to both levels.
Displaying IPv4 IS-IS information
You can display the following information:

IS-IS configuration in the running-config” on page 293
• Name mappings – “Displaying the name mappings” on page 294
• Neighbor information – “Displaying neighbor information” on page 294
• Neighbor adjacency changes – “Displaying IS-IS Syslog messages” on page 296
• Interface information – “Displaying interface information” on page 297
• Route information – “Displaying route information” on page 301
• LSP database entries – “Displaying LSP database entries” on page 302
