CHAPTER 9
CFM Commands
Use these commands to configure the Connectivity Fault Management (CFM) on the Switch.
9.1 CFM Term Definition
This section lists the common term definition which appears in this chapter. Refer to User’s
Guide for more detailed information about CFM.
Table 26 CFM Term Definitions
TERM DESCRIPTION
CFM CFM (Connectivity Fault Management) is used to detect and analyze connectivity
faults in bridged LANs.
MD An MD (Maintenance Domain) is part of a network, where CFM can be done. The
MD is identified by a level number and contains both MEPs and MIPs. The Switch
supports up to eight MD levels (0 ~ 7) in a network. You can create multiple MDs
on one MD level and multiple MA groups in one MD.
MA An MA (Maintenance Association) is a group of MEPs and identified by a VLAN
ID. One MA should belong to one and only one MD group.
MEP An MEP (Maintenance End Point) port has the ability to send and reply to the
CCMs, LBMs and LTMs. It also gets other MEP port information from neighbor
switches’ CCMs in an MA.
MIP An MIP (Maintenance Intermediate Point) port forwards the CCMs, LBMs, and
LTMs and replies the LBMs and LTMs by sending Loop Back Responses (LBRs)
and Link Trace Responses (LTRs).
Connectivity
Check
Connectivity Check (CC) enables an MEP port sending Connectivity Check
Messages (CCMs) periodically to other MEP ports. An MEP port collects CCMs to
get other MEP information within an MA.
Loop Back Test Loop Back Test (LBT) checks if an MEP port receives its LBR (Loop Back
Response) from its target after it sends the LBM (Loop Back Message). If no
response is received, there might be a connectivity fault between them.
Link Trace Test Link Trace Test (LTT) provides additional connectivity fault analysis to get more
information on where the fault is. In the link trace test, MIP ports also send LTR
(Link Trace Response) to response the source MEP port’s LTM (Link Trace
Message). If an MIP or MEP port does not respond to the source MEP, this may
indicate a fault. Administrators can take further action to check and resume
services from the fault according to the line connectivity status report.

- Weighted fair queuing wfq guarantees each queue s minimum bandwidth based on its bandwidth weight portion when there is traffic congestion wfq is activated only when a port has more traffic than it can handle queues with larger weights get more guaranteed bandwidth than queues with smaller weights this queuing mechanism is highly efficient in that it divides any available bandwidth across the different traffic queues by default the weight for q0 is 1 for q1 is 2 for q2 is 3 and so on guaranteed bandwidth is calculated as follows 178
- Weighted round robin scheduling wrr services queues on a rotating basis and is activated only when a port has more traffic than it can handle a queue is a given an amount of bandwidth based on the queue weight value queues with larger weights get more service than queues with smaller weights this queuing mechanism is highly efficient in that it divides any available bandwidth across the different traffic queues and returns to queues that have not yet emptied hybrid mode wrr spq or wfq spq some switch models allow you to configure higher priority queues to use spq and use wrr or wfq for the lower level queues 178
