Command Usage
• Address monitoring must be enabled on a QinQ tunnel port to properly
forward traffic for the internal management VLANs (VIDs 247-249)
between the QinQ tunnel port and the SBC connected to port 28.
• Before enabling address monitoring, the ECN330-switch must first be
set to QinQ mode with the
system mode
command (section 7.5.7 on
page 552), and the access port set to a QinQ tunnel port with the
switchport mode dot1q-tunnel
command (section 7.17.26 on
page 884).
• When address monitoring for the QinQ tunnel port is enabled, and
incoming traffic is tagged for the internal management VLAN (247) or
the FSA VLAN (249), an outer VLAN tag of 4093 is inserted and the
packet redirected to port 28. The outer tag is removed at port 28 and the
SBC processes the packet. When a packet for VLAN 247 or 249 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.
• When address monitoring for the QinQ tunnel port is enabled, and the
tunnel port is a member of the dynamic management VLAN (248) and
an incoming untagged packet enters this port, the ECN330-switch
inserts an inner dummy tag, an outer tag of 248, and the packet is
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
