In an Extended Edge Switching environment, shows the bridge port extender (BPE) topology that is connected to the specified native cascade port.
vpex | Specifies Virtual Port Extender (VPEX). |
port | Specifies topology information for VPEX slots attached to a specified native VPEX cascade port on the controlling bridge (CB). |
port_num | Specifies the native VPEX cascade port number. |
summary | Includes connected VPEX slot numbers only. Default behavior when port is not specified. |
detail | Selects including VPEX slot interconnections. Default behavior when port is specified. |
If a port is not specified, then summary (connected VPEX slot numbers only) information appears by default; if a port is specified, then detailed (VPEX slot interconnections) information appears by default.
If a port is not entered or summary is selected, all topologies appear (summary mode). Only the native cascade port or MLAG and a list of slots appear in summary mode.
If a port is entered or detail is selected, detailed mode information appears. For a ring topology, the command shows both cascades that form a ring, including the dynamically created cascade ports and assigned backup roles. Thus the BPE in each cascade appears twice, one in each cascade.
Severed rings also appear as a pair of cascades with all upstream or cascade ports not being identified as backup. The cascades also indicate that the BPE has been dynamically created (configured) in its position in the cascade. If a native cascade port is not specified, then all topologies appear. Otherwise, only the topology connected to the CB‘s cascade port appears.
For slots configured using virtual MLAG, instead of the native cascade port, the MLAG ID appears.
