Cisco XR 12000 SIP-501 Overview
SPA Interface Addresses on the Cisco XR 12000 SIP-501
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 XR 12000 SIP-601 has two subslots 0 (left) and 1 (right). For example, the interface
address of a 1-port SPA located in the second SIP subslot, where the SIP is inserted into router line card
slot 3 is 3/1/0.
shows the slot, subslot, and port locations for the 1-Port 10-Gigabit Ethernet
SPA and the 10-Port Gigabit Ethernet SPA.
