redirected to port 28. The outer VLAN tag is retained because port 28
is tagged member of 248, and the SBC processes the packet. When a
packet for VLAN 248 is sent from port 28 to the tunnel port, a single
inner tag is used and the packet is sent as in any normal forwarding
operation. However, note that the tag will stripped from the packet by the
tunnel port because it is an untagged member or VLAN 248.
When a tunnel port changes to QinQ Tunnel mode from normal mode,
address monitoring is automatically enabled on this port, and all
dynamic MAC address entries are deleted. If a new address entry is
subsequently learned at the tunnel port, a static address entry for any
internal management VLAN is added to the address table. If multiple
internal management VLANs are configured, multiple entries are added
to the address table.
When a tunnel port changes to normal mode from QinQ Tunnel mode,
address monitoring is automatically disabled on this port, and all static
internal management VLAN address entries are deleted.
If the internal management VLAN ID is changed, all dynamic MAC
address and static internal management VLAN address entries are
deleted.
When the PVID of a tunnel port is changed, all dynamic MAC address
and static internal management VLAN address entries are deleted.
