Switching

I have a strange one:

# show vlans
vrrp-vlan {
    vlan-id 100;
    l3-interface vlan.0;
}

# show interfaces

ge-1/0/4 {
    mtu 9192;
    unit 0 {
        family ethernet-switching {
            port-mode access;
            vlan {
                members vrrp-vlan;
            }
        }
    }
}
ge-1/0/5 {
    mtu 9192;
    unit 0 {
        family ethernet-switching {
            port-mode trunk;
            vlan {
                members vrrp-vlan;
            }       
        }
    }
}

vlan {              
    per-unit-scheduler;
    unit 0 {
        family inet {
            rpf-check fail-filter rpf-inet;
            address 1.1.1.3/24 {
                vrrp-group 1 {
                    virtual-address 1.1.1.1;
                    priority 90;
                }
            }
        }
    }
}

yet when i do a show interface vlan:

VLAN: vrrp-vlan, Created at: Fri Mar 26 22:55:45 2010
802.1Q Tag: 100, Internal index: 3, Admin State: Enabled, Origin: Static
Protocol: Port Mode, Mac aging time: 300 seconds
Number of interfaces: Tagged 1 (Active = 1), Untagged  1 (Active = 0)
      ge-1/0/5.0*, tagged, trunk
      ge-1/0/4.0, untagged, access

# run show interfaces vlan.0
  Logical interface vlan.0 (Index 69) (SNMP ifIndex 502)
    Flags: Link-Layer-Down SNMP-Traps 0x4000 Encapsulation: ENET2
    Bandwidth: 0
    Input packets : 0
    Output packets: 1
    Security: Zone: Null
    Protocol inet, MTU: 1500
      Flags: uRPF
      Addresses, Flags: Dest-route-down Is-Preferred Is-Primary
        Destination: 1.1.1/24, Local: 1.1.1.3,
        Broadcast: 1.1.1.255

it seems that if I have no active access ports in the vlan the vlan interface goes down!!!

how can I force it up?

hi,

You're right

Your vlan interface will be up when at least one interface in the vlan will be up.

I don't know any way to put it in loopback mode (as it exists on Extreme switches for example)

If you ony need an address for test  or for management just use a loopback interface (lo0.x)

If anyone knows if it's possible please tell us !

Hope This will Help You

Hi, did you manage to solve this issue?

We are trying to do it but haven't managed yet to do so.

Thanks!
