Connecting Trunks

The sections that follow contain basic information on how to set up the two types of trunks on the

IGX node. The two trunk types are FastPacket and ATM. The supported line types are OC3/STM1,

T3, E3, T1, Y1, and E1. The card sets described in this section are the network trunk module (NTM).

The universal switching module (UXM-E) is a dual-purpose, ATM cell-based card and has its own

section that includes information for trunk-mode conﬁguration and port-mode conﬁguration.

Setting Up a UXM-E

To set up a UXM-E attach cables and enter commands at the command-line interface (CLI). For

detailed information regarding the UXM-E, refer to the Cisco IGX 8400 Series Reference. The

Cisco IGX 8400 Series Reference contains crucial information on, for example, supported endpoints,

connection types, allocation of cellbus bandwidth, and the logical trunk feature called Inverse

Multiplexing Over ATM (IMA).

You can specify the mode of the UXM-E through Cisco WAN Manager or the CLI. The UXM-E

card set goes into the mode determined when you activate the ﬁrst port. If you activate a logical port

to be a trunk by using the uptrk command, for example, the UXM-E goes into trunk mode. If you

use upln to activate a line as a UNI port to CPE or an NNI to another network, the UXM-E goes into

port mode.

For a summary of commands you use to bring up an IGX node, refer to the section "IGX

Conﬁguration Summary" on page 49 at the end of this chapter.

Bringing Up a UXM-E Trunk

If you are not familiar with precautions for card insertion, see the section "Preparing the Cards" on

page 1.

To attach the cables to a back card:

Step 1

Step 2

Step 3

Bring each cable through the opening at the top or bottom of the cabinet (however

appropriate) and along the back of the IGX enclosure. (See Figure 3-7.)

If the unit has the optional cable manager, you can use it to help route the cables. (See

Figure 3-7.)

Connect the cables to the connectors on the back card. (See Figure 3-7.)
