PV-FC-180 communication / ping loss when tunnel is enabled

Information

 
TitlePV-FC-180 communication / ping loss when tunnel is enabled
Symptoms
PV-FC-180 loses communication to network when tunnel mirror enabled for Purview collection
Environment
  • PV-FC-180
  • SSA
  • Purview mirror with GRE tunnel
Cause
By default the tun.0.1 interface will be in VLAN 1.  If the Management IP address is also configured in VLAN 1 this will cause management traffic to go over the tunnel bridge port instead of out front panel ports
Resolution
Two options exist to resolve this issue:
  • Change the VLAN that the management interface is in if possible
  • Move the tunnel interface to a non-used VLAN such as:
set vlan create 2000
set port vlan tbp.0.1 2000 modify-egress
