Figure 53. C1048P Port Numbering
On a C1048P port extender, 10/100/1000BASE-T ports on the front panel are numbered from 1 to 48.
● Odd-numbered ports 1-47 are on top; even-numbered ports 2-48 are on the bottom.
● A yellow PE port number indicates that the port is PoE-enabled.
● The two 10GbE SFP+ ports, which are used only for uplinks to an attached C9010, are numbered 1 and 2.
After the initial PE provisioning is performed, you can configure L2 and other software features by entering CLI commands on
the C9010 console. C1048P interfaces are identified in the command syntax:
interface peGigE pe-id/pe-stack—unit-id/port-number
● pe-id is a port-extender ID number from 0 to 255.
● pe-stack-unit-id is a PE stack-unit number from 0 to 7
● port-number is a port number from 1 to 48.
interface peTenGigE pe-id/unit-number/port-id
● pe-id is a port-extender ID number from 0 to 255.
● unit-number is a PE stack-unit number from 0 to 7
● port-id is from 25 to 28 or 49 to 52 depending on the PE.
NOTE:
PE configuration commands are only available after you enable the extended-bridge feature. See Enabling the Port
Extender Feature.
NOTE: To locate a C1048P, enter the location-led pe pe-id stack-unit unit-number command in EXEC
Privilege mode to toggle the location LED for the PE on and off.
