LMS4.1 topologyview N7K missing links

[guidohagenauer]

Hello,

I work with the topologyview in LMS 4.1.

I can see all the links between the differrent switches (N7K, 3750, 3040).

I miss only the links between the different N7K's. This links have one special thinks: they are configured as "  rate-mode dedicated force"

In the N7K cli this interfaces are displayed with the SN too.

sw-bb13# show cdp nei

The links to sw-bb11 and sw-bb21 are not painted in the topoloyview.

Both sides need to be in each other in the CDP tables.

Check if cdp is disabled on a port

Cheers,

Michel

Hello Michel,

all the ports between the 4 N7K (this are 18 10GE ports) are with CDP enabled. You can see allways each other N7K in the different CDP neighbor tables.

I've seen a few ocasions where a device was discovered and where gradually links were added, that some links were not discovered.

In another view, not the the layer2 view, but in a custom backbone group, all the links were present. but in the layer 2 view this did not reflect 

Removing and re-adding the devices where the links were missing was the only way to fix it.

Cheers,

Michel
