Most engineers I've met know about the show les command. There is also a show les summary command. Using show les summary can make your work a lot less tedious. This is what you get when you run the show les summary command from the command line on a 5000BH/C100:
Oxford Center SW 011A:Command > show les summ
LES/BUS 1 ElanType=AF-LANE802.3 ElanName=oxfordserver ElanID: 0 Status=Up
Coop LES/BUS Pairs=3

. . . This is a handy command for a couple of reasons. First, if you just want to look at the status of one LES/BUS pair, you can use this command to find out what that LES/BUS pair's number is, and then run show les X, where X is the listed number. You get the information you want without having to wade through all the other LES/BUS pair info that merely executing show les would give you. Second, you can get a high-level feel for whether all of the LES/BUS pairs with Coop partners are communicating with their partners.
How does this work? Easy. Let's look at the output from one of the LES/BUS pairs again:
LES/BUS 2 ElanType=AF-LANE802.3 ElanName=oxfordclient ElanID: 0 Status=Up
Coop LES/BUS Pairs=3
NumOutLES Vcc:3 NumInLES Vcc:3NumOutBUS VCCs:3 NumInBUS VCCs: 3
Num LES_Clients:2 Num BUS_Clients:2
I've highlighted the relevant parts. The number in red is the number of cooperating LES/BUS pairs this LES/BUS thinks it should be working with. The numbers in blue are the numbers of incoming and outgoing VCCs the switch has established with cooperating LES/BUS partners for this ELAN. The red and blue numbers should match. If they do match, then all is well. If they don't match, further investigation is in order.
Similar help is available for checking LEC status. (Nortel tends to use LEC and vport interchangably. There is a reason that the term vport exists -- it was the term for the virtual port that a 1483 bridged PVC terminated on in a bridge group in a pre-LANE Centillion environement) Anyway, just as there is a show les summary, there is a show vport summary command:
Oxford Center SW 011A:Command > show vport summ

The fourth collumn shows the current operating state for each vport. In this case all of them are in Operat (Operational). You might see LecsCo when the LEC (if it is set up to use automatic configuration) is looking for the LECS. There are other states, such as Unknow when a LEC can't find it a LES to register with.
If you have a vport that is not in Operat you can look up just that vport's information by running show vport status X, where X is the number of the vport (listed as Idx). Like show les X, show vport status X is much more effiecnt than wading through all the output from a show vport status all.
