Virtual access interface - Why?

Pradeep H A

Level 1

Hi all,

I have 2620XM router. on which I see a virtual-access1 interface. there are no virtual-templates configured on the router neither there is any IP configuration on it. What is the purpose of having such an interface & it seems it was automatically created?

Router#sh ip int brief

Interface                        IP-Address      OK?         Method   Status             Protocol

FastEthernet0/0            10.123.1.1       YES        NVRAM     up                    up

Serial0/0                       unassigned      YES        NVRAM     up                    up

Serial0/0.100                <<<IP>>>>      YES        NVRAM     up                    up

Virtual-Access1            unassigned      YES        unset         up                    up

Loopback0                    <<<<IP>>>      YES       NVRAM      up                    up

Router#sh int Virtual-Access1

Virtual-Access1 is up, line protocol is up

  Hardware is Virtual Access interface

  MTU 1492 bytes, BW 100000 Kbit, DLY 100000 usec,

     reliability 255/255, txload 1/255, rxload 1/255

  Base PPPoE vaccess, loopback not set

  DTR is pulsed for 5 seconds on reset

  Last input never, output never, output hang never

  Last clearing of "show interface" counters 18w0d

  Input queue: 0/4096/0/0 (size/max/drops/flushes); Total output drops: 0

  Queueing strategy: fifo

  Output queue: 0/40 (size/max)

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

     0 packets input, 0 bytes, 0 no buffer

     Received 0 broadcasts, 0 runts, 0 giants, 0 throttles

     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

     0 packets output, 0 bytes, 0 underruns

     0 output errors, 0 collisions, 0 interface resets

     0 output buffer failures, 0 output buffers swapped out

     0 carrier transitions

Router#sh run int Virtual-Access1

Building configuration...

Current configuration : 61 bytes

!

interface Virtual-Access1

no ip address

ip mtu 1500

end

Thanks in advance
