Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 397)

The following illustrates configuration in no-default-native-VLAN trunk mode.
switch(config)# int vlan 5000
switch(config)# int vlan 6000
switch(config-Vlan-6000)# transport-service 60
switch(config)# int vlan 7000
switch(config-Vlan-7000)# transport-service 70
In the new mode, the default behavior is to drop all packets.
(config)# int te 1/0/1
(config-if-te-1/0/1)# switchport mode trunk-no-default-native
VLAN configuration similar to that of regular trunk mode can be achieved
explicitly after VLAN 1 is configured as a tagged VLAN.
switch(config-if-te-1/0/1)# switchport trunk allow vlan add 1
The following creates native VLAN 10. All service and transport VFs can continue
to coexist on the same port.
switch(config-if-te-1/0/1)# switchport trunk native-vlan-untagged 10
switch(config-if-te-1/0/1)# switchport trunk allow vlan 6000 ctag 100-200
switch(config-if-te-1/0/1)# switchport trunk default-vlan 7000
The following accepts ingress tagged or untagged frames, but egress frames
must be tagged only. This is not allowed in default-VLAN trunk mode.
switch(config-if-te-1/0/1)# switchport trunk native-vlan-xtagged 10 egress tagged
The following classifies a tagged native VLAN to service VF 5000.
switch(config-if-te-1/0/1)# switchport trunk native-vlan-xtagged 5000 ctag 10 egress
tagged
The following classifies VLAN 10 to transport VF 6000. Because this native
VLAN is a transport VF, the option for egress is any.
switch(config-if-te-1/0/1)# switchport trunk native-vlan-xtagged 6000 ctag 10 egress
any
switch(config-if-te-1/0/1)# switchport trunk allow vlan 6000 ctag 100-200
The following configurations are valid or invalid in no-default-native-VLAN mode.
switch(config)# int te 5/0/1
switch(config-if-te-5/0/1)# switchport mode trunk-no-default-native
switch(config-it-te-5/0/1)# switchport trunk tag-native
ERROR: Port mode not set to trunk
switch(config-it-te-5/0/1)# switchport trunk native vlan 2
ERROR: Port mode not set to trunk
# C-TAG classification to service or transport VF mapping is still 1 to 1.
# Rejected as duplicate classification even when same CTAG-to-VF mapping is given.
switch(config-if-te-5/0/1)# switchport trunk native-vlan-xtagged 6000 ctag 10 egress
any
switch(config-if-te-5/0/1)# switchport trunk allow vlan add 6000 ctag 10-20
ERROR: ctag already used in other classification
switch(config-if-te-5/0/1)# switchport trunk allow vlan 7000 ctag 10
ERROR: ctag already used in other classification
Configuring and managing Virtual Fabrics
The fabric must be in logical chassis cluster mode for the configuration and management of the Virtual
Fabrics feature. Whenever changes are made, they are saved automatically. Ensure that the fabric is in
logical chassis cluster mode before attempting to configure or manage this feature.
Refer also to Virtual Fabrics overview on page 375.
