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

Table 4-10 Configurable Trunk Characteristics

Interface Type	Configurable Parameters
OC3 (STM1) SMF,	• HCS masking (on or off)
EL, and MMF	• Payload scramble (on or off)
	• Cell (line) framing (STS/SONET or STM/SDH)
	• Frame scramble (on or off)
T3	• HCS masking (on or off)
	• Payload scramble (on or off)
	• Cell (line) framing can be header error correction (HEC) or PLCP
	• Cable length (0 to 255 feet or greater than 255 feet)
E3	• HCS masking (on or off)
	• Payload scramble (on or off)
	• Cell (line) framing is fixed as header error Correction (HEC)
	• Cable length (0 to 255 feet or greater than 255 feet)
