Release 12.0(32)SY1, OL-8831-01, Rev. G6, July 19, 2007
Chapter 1 Overview: Cisco 12000 Series Router SPA Interface Processors
Cisco 12000 SIP-400 Overview
SPA Interface Addresses on the Cisco 12000 SIP-400
A Cisco 12000 Series Router identifies a SPA interface address by its SIP slot number, SPA subslot, and
port number on the SPA, in the format
slot/subslot/port
. Subslots and ports are numbered starting from
0, so each Cisco 12000 SIP-400 has four subslots. A 4-port SPA would have ports 0 to 3. For example,
the interface address of the second port on a 4-port SPA located in the first SIP subslot, where the SIP is
inserted into router line card slot 6 is 6/0/1.
