Verifying Routed VLAN Interface Status and Statistics
Purpose
Determine status information and traffic statistics for routed VLAN interfaces (RVIs) by using the following commands:
Action
Display RVI interfaces and their current states:
user@switch> show interfaces vlan terse Interface Admin Link Proto Local Remote vlan up up vlan.111 up up inet 111.111.111.1/24
Display Layer 2 VLANs, including any tags assigned to the VLANs and the interfaces associated with the VLANs:
user@switch> show vlans Name Tag Interfaces
default
None
employee-vlan 20
ge-1/0/0.0, ge-1/0/1.0, ge-1/0/2.0
marketing 40
ge-1/0/10.0, ge-1/0/20.0, ge-1/0/30.0
support 111
ge-0/0/18.0

Display Ethernet switching table entries for the VLAN that is attached to the RVI:
user@switch> show ethernet-switching table
Ethernet-switching table: 1 entries, 0 learned VLAN MAC address Type Age Interfaces support 00:19:e2:50:95:a0 Static - Router
Display an RVI’s ingress-counting statistics with either the show interfaces vlan detail command or the show interfaces vlan extensive command. Ingress counting is displayed as Input bytes and Input packets under Transit Statistics.
user@switch> show interfaces vlan.100 detail Logical interface vlan.100 (Index 65) (SNMP ifIndex 503) (HW Token 100) (Generation 131) Flags: SNMP-Traps 0x4000 Encapsulation: ENET2 Traffic statistics: Input bytes: 17516756 Output bytes: 411764 Input packets: 271745 Output packets: 8256 Local statistics: Input bytes: 3240 Output bytes: 411764 Input packets: 54 Output packets: 8256 Transit statistics: Input bytes: 17513516 0 bps Output bytes: 0 0 bps Input packets: 271745 0 pps Output packets: 0 0 pps Protocol inet, Generation: 148, Route table: 0 Flags: None Addresses, Flags: iS-Preferred Is-Primary Destination: 50.1.1/24, Local: 50.1.1.1, Broadcast: 50.1.1.255, Generation: 136
Meaning
- show interfaces vlan displays a list of interfaces, including RVI interfaces, and their current states (up, down).
- show vlans displays a list of VLANs, including any tags assigned to the VLANs and the interfaces associated with the VLANs.
- show ethernet-switching table displays the Ethernet switching table entries, including VLANs attached to the RVI.
- show interfaces vlan detail displays RVI ingress counting as Input Bytes and Input Packets under Transit Statistics.
