Super VLAN Troubleshooting
Supervlan and these functions (VRRP, dynamic VLAN, private VLAN, multicast VLAN,
etc.) are mutually exclusive, so they should not be used at the same time.
arp-proxy of subvlan takes effect to only one subvlan. Flow received by VLAN with
arp-proxy can be forwarded to other VLAN. When two devices send flows to each
other at different subvlan, please enable arp-proxy function on two subvlans.
Sub vlan can not set layer-3 interface.
When creating/deleting supervlan, VLAN needs to ensure no layer-3 interface, if not,
it will result in error.
If interface of supervlan specifies IP address range, but do not specify address range
of subvlan, address range set by interface is standard. If both interface and subvlan
specify IP address range, please check whether packets are within subvlan address
range firstly, second, check whether packets are within interface address range. After
that, packets can be processed other operations.
When setting supervlan or subvlan, VLAN must be exist, it can be set.
When port mode is set as trunk, it will automatically filter supervlan from allow-vlan.
