Examples: Interface Naming

This section provides examples of naming interfaces. For an illustration of where slots, PICs, and ports are located, see Figure 2.

Figure 2: Interface Slot, PIC, and Port Locations

For an FPC in slot 1 with two OC3 SONET/SDH PICs in PIC positions 0 and 1, each PIC with two ports uses the following names:

so-1/0/0.0

so-1/0/1.0

so-1/1/0.0

so-1/1/1.0

An OC48 SONET/SDH FPC in slot 1 and in concatenated mode appears as a single FPC with a single PIC, which has a single port. If this interface has a single logical unit, it has the following name:

so-1/0/0.0

An OC48 SONET/SDH FPC in slot 1 and in channelized mode has a number for each channel. For example:

so-1/0/0:0

so-1/0/0:1

For an FPC in slot 1 with a Channelized OC12 PIC in PIC position 2, the DS3 channels have the following names:

t3-1/2/0:0

t3-1/2/0:1

t3-1/2/0:2

...

t3-1/2/0:11

For an FPC in slot 1 with four OC12 ATM PICs (the FPC is fully populated), the four PICs, each with a single port and a single logical unit, have the following names:

at-1/0/0.0

at-1/1/0.0

at-1/2/0.0

at-1/3/0.0 

In a routing matrix on the T640 routing node labeled lcc1, for an FPC in slot 5 with four SONET OC192 PICs, the four PICs, each with a single port and a single logical unit, have the following names:

so-13/0/0.0

so-13/1/0.0

so-13/2/0.0

so-13/3/0.0 

For an FPC in slot 1 with one 4-port BRI interface card, port 4 has the following name:

br-1/0/4

The first B channel, the second B channel, and the control channel have the following names:

bc-1/0/4:1

bc-1/0/4:2

dc-1/0/4:0
