network-operator
Parameters
instance instance-list: Specifies a space-separated list of up to 10 MSTI items. Each item specifies
an MSTI or a range of MSTIs in the form of instance-id1 [ to instance-id2 ]. The value for instance-id2
must be equal to or greater than the value for instance-id1. The value range for the instance-id
argument is 0 to 4094, and the value 0 represents the CIST.
vlan vlan-id-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a
VLAN or a range of VLANs in the form of vlan-id1 [ to vlan-id2 ]. The value for vlan-id2 must be equal
to or greater than the value for vlan-id1. The value range for the vlan-id argument is 1 to 4094.
slot slot-number: Specifies an IRF member device by its member ID. If this option is not specified,
this command applies to all member devices in the IRF fabric.
Usage guidelines
In STP or RSTP mode, the output is sorted by port role calculation time.
In PVST mode, the command output is sorted by VLAN ID and by port role calculation time in each
VLAN.
•
If you do not specify a VLAN, this command applies to all VLANs.
•
If you specify a VLAN list, this command applies to the specified VLANs.
In MSTP mode, the command output is sorted by MSTI ID and by port role calculation time in each
MSTI.
•
If you do not specify an MSTI, this command applies to all MSTIs.
•
If you specify an MSTI list, this command applies to the specified MSTIs.
