CHAPTER 10
CFM Commands
Use these commands to configure the Connectivity Fault Management (CFM) on the Switch.
10.1 CFM Overview
The route between two users may go through aggregated switches, routers and/or DSLAMs
owned by independent organizations. A connectivity fault point generally takes time to
discover and impacts subscribers’ network access. IEEE 802.1ag is a Connectivity Fault
Management (CFM) specification which allows network administrators to identify and
manage connection faults in order to ease management and maintenance. Through discovery
and verification of the path, CFM can detect and analyze connectivity faults in bridged LANs.
The figure shown below is an example of a connection fault between switches in the service
provider’s network. CFM can be used to identify and management this kind of connection
problem.
Figure 1 Connectivity Fault Example
10.1.1 How CFM Works
CFM sends pro-active Connectivity Check (CC) packets between two CFM-aware devices in
the same MD (Maintenance Domain) network. An MA (Maintenance Association) defines a
VLAN and associated ports on the device under an MD level. In this MA, a port can be an
MEP (Maintenance End Point) port or an MIP (Maintenance Intermediate Point) port.

- Example enabling ipv6 on windows xp 2003
- Ethernet switch cli reference guide
- Chapter 33 ipv6 commands
- By default windows xp and windows 2003 support ipv6 this example shows you how to use the ipv6 install command on windows xp 2003 to enable ipv6 this also displays how to use the ipconfig command to see auto generated ip addresses
- This example shows you how to access the switch using http on windows xp
- Make sure you have enabled ipv6 on your computer see section 33 use the ipconfig command in the command prompt to check the ipv6 address on your computer the example uses an interface with address fe80 2d0 59ff feb8 103c to
- It s recommended to use internet explorer 7 or firefox to access the switch s web gui
- Ipv6 is installed and enabled by default in windows vista use the ipconfig command to check your automatic configured ipv6 address as well you should see at least one ipv6 address available for the interface on your computer
- How you access the switch using http varies depending on the operating system os and the type of browser you use and the type of address you want to access
- Example http accessing the switch using ipv6
- In windows xp 2003 vista use the ipconfig command in the command prompt to check the ipv6 address on your computer each ipv6 address is appended with a percentage and the ethernet interface s interface identifier of the ethernet interface with which the address associates this is an example to show you how to ping from a windows xp computer to the switch
- Example ipv6 ping on windows xp 2003 vista
- Ethernet switch cli reference guide
- Check the switch ipv6 address es to which you want to ping in this example there are two ipv6 addresses in vlan 1 one is a link local address fe80 219 cbff fe00 1 64 and the other one is a global address 2001 1234 64
- Chapter 33 ipv6 commands
- Make sure you have enabled ipv6 on your computer see section 33 on page 160 use the ipconfig command in the command prompt to check this in this example the address fe80 2d0 59ff feb8 103c is used to ping the switch so the 4 of the ethernet interface identifier will be used later to ping
- Ping to the switch s link local address when you ping a link local address from a windows xp computer you have to append the interface identifier of the ethernet interface from which you want to ping
- Ping to the switch s global address when you ping a global address on a windows xp computer you just need to enter an ipv6 destination address

- 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
- 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
