Configuring MPLS VLLs
4
•
In the case of an untagged port, an endpoint is identified by the physical port alone, and the
packets are sent in untagged Ethernet format.
•
In the case of a dual-tagged port, the packets contain both an outer VLAN tag and an inner
VLAN tag.
Configuring VLL endpoint over FDP/CDP enabled interface
Configuring VLL endpoint over an FDP/CDP enabled interface will implicitly disable FDP/CDP
configuration and also will be enable back implicitly when the VLL endpoint is deleted on that
specific interface, considering FDP/CDP is enabled globally.
Info messages will be displayed to notify the user as below for these cases:
For example, when VLL endpoint is created the info messages displayed are as below.
1
When only FDP is enabled globally.
Brocade(config-mpls-vll-vll1-vlan-100)#tag eth 4/3 eth 4/5 eth 4/7
info- FDP is disabled on port 4/3
info- FDP is disabled on port 4/5
info- FDP is disabled on port 4/7
2
When only CDP is enabled globally.
Brocade(config-mpls-vll-vll1-vlan-100)#tag eth 4/3 eth 4/5 eth 4/7
info- CDP is disabled on port 4/3
info- CDP is disabled on port 4/5
info- CDP is disabled on port 4/7
3
When both FDP/CDP is enabled globally.
Brocade(config-mpls-vll-vll1-vlan-100)#tag eth 4/3 eth 4/5 eth 4/7
info- FDP/CDP is disabled on port 4/3
info- FDP/CDP is disabled on port 4/5
info- FDP/CDP is disabled on port 4/7
For example, when VLL endpoint is deleted the info messages are displayed as below.
1
When only FDP is enabled globally.
Brocade(config-mpls-vll-vll1-vlan-100)#no tag eth 4/3 eth 4/5 eth 4/7
info- FDP is enabled on port 4/3
info- FDP is enabled on port 4/5
info- FDP is enabled on port 4/7
2
When only CDP is enabled globally.
Brocade(config-mpls-vll-vll1-vlan-100)#no tag eth 4/3 eth 4/5 eth 4/7
info- CDP is enabled on port 4/3
info- CDP is enabled on port 4/5
info- CDP is enabled on port 4/7
3
When both FDP/CDP is enabled globally.
Brocade(config-mpls-vll-vll1-vlan-100)#no tag eth 4/3 eth 4/5 eth 4/7
info- FDP/CDP is enabled on port 4/3
info- FDP/CDP is enabled on port 4/5
info- FDP/CDP is enabled on port 4/7
NOTE
If the VLL endpoint is configured over a globally enabled FDP/CDP interface, the show run command
does not display FDP/CDP information for that specific interface.
