 Trunk Cards 4-19

Activation and Configuration of a UXM-E in Trunk Mode

When you insert a new UXM-E into the backplane or apply power to the IGX node, UXM-E
firmware reports the card type and number of physical lines on the back card. Switch software can
then determine the allowed range and characteristics of trunks for you to configure. Software thus
prevents you from exceeding the maximum number of trunks on the switch as you activate them
through either Cisco WAN Manager or uptrk on the CLI.

Table 4-10 shows the trunk characteristics you can configure for each interface type through either
Cisco WAN Manager or the cnftrk command on the CLI. Table 4-10 also shows the fixed
parameters.
