2) Interface numbering
The following are interface numbering rules with the Router 6000:
z The interfaces are represented by interface-type X/Y/Z, where interface-type can
be serial, asynchronous, ethernet or ATM, and so on; X specifies the slot number;
Y specifies the daughter card number (it is 0 when no daughter card is installed);
and Z specifies the interface sequence number.
z As shown in the above figures, different interfaces on an interface module share
the same slot number X.
z For every interface, Y starts from 0 and Z indicates the interface sequence on the
interface module, from left to right.
