[j-nsp] SRX4200 - Mysterious vlan interface

[Youssef Bengelloun-Zahr]

Hello j-nsp community,

we have migrated to an SRX4200 cluster (running junos 15.1X49-D110), and
I'm seeing since then a new interface call vlan but with no presence in the
configuration :

root at fw01-par01> show interfaces vlan
Physical interface: vlan   , Enabled, Physical link is Down
  Interface index: 152, SNMP ifIndex: 508
  Type: VLAN, Link-level type: VLAN, MTU: 1518, Speed: 1000mbps
  Device flags   : Present Running Down
  Interface flags: Hardware-Down
  Link type      : Full-Duplex
  CoS queues     : 8 supported, 8 maximum usable queues
  Current address: 30:b6:4f:61:cd:af, Hardware address: 30:b6:4f:61:cd:af
  Last flapped   : 2017-09-19 20:42:33 CEST (2w1d 14:42 ago)
  Input rate     : 0 bps (0 pps)

root at fw01-par01> show configuration interfaces vlan

interface type vlan is not supported in this platform.


Does anyone what this interface is about ?

Best regards.
