Monitoring the status of devices in a VPLS network in a Provider’s Maintenance Domain
6
Support for IEEE 802.1ag CFM for Provider Bridges
(PB) and Provider Backbone Bridges (PBB)
The device support the following single tagging and double tagging cases:
• MEP (up/down) and MIP on C-VLANs
• MEP (up/down) and MIP on S-VLANs - The ability to change tag-type 88a8 to S-VLANs
The Brocade NetIron CES supports both of the above capabilities in the following scenarios:
• MEP (up/down) and MIP on C-VLANs
• MEP (up/down) and MIP on S-VLANs -The ability to change tag-type 88a8 to S-VLANs
• MEP on C-VLANs (extended to both default ESI and non-default ESI)
NOTE
The C-VLAN may be a child of another ESI or could be “stand-alone”.
• MEP on S-VLANs in an ESI
NOTE
The S-VLAN may be a child of another ESI or could be “stand-alone”
• MIP on standalone C-VLANs and stand-alone S-VLANs on a device (i.e. C-VLANs that are not a
client of another ESI or S-VLANs that are not a client of another ESI).
The following configurations are not supported on the Brocade NetIron CES devices:
• Handling MIP on a C-VLAN that is a client of an S-VLAN
• Handling MIP/MEP on a B-VLAN
• Handling MIP on an S-VLAN that is a client of a B-VLAN
802.1ag over PBB sub-second timer support
NOTE
The sub-second timer functionality is not supported on NetIron CES devices.
The ccm-interval command sets the time interval between two successive Continuity Check
messages (CCMs) that are sent by MEPs in the specified Maintenance Domain. The default value is
10 seconds. There is support for sub-second timers 3.3 ms, 10 ms and 100 ms. The ISID CFM can
be used in PBB networks and CFM monitoring between Backbone Edge Bridges.
The sub-second CCM interval is supported for the following scenarios:
• 802.1ag over Regular Vlan
• 802.1ag over ESI VLAN
• 802.1ag over VPLS
The following messages are supported for sub-second CCM interval:
• Loop Back Message and Reply (LBM, LBR)
• Link Trace Message and Reply (LTM, LTR)
• Delay Measurement Message and Reply (DMM, DMR)
