max locate size

[aattarenzio]

hello, does anyone know the max locate size that a SNASw router will set for the locate process ?

For VTAM is 16K, for the Cisco Snasw ?

I can't find this on the doc and I think my "location" problem depends on this.

Many thanks in advance to the people that will reply.

Cheers, Alex

Hi Alex,

in IOS 12.1 and 12.2 snaswitch is bounded by a locate size of 1K, which means if you have more than 8-10 uplinks defined you may run out of room and encounter less-desireable session paths or outright session failures.

An enhancement was added in IOS 12.2T to make the size 4K. If you want to stay with IOS 12.1 or 12.2 (because they are more stable than 12.2T), you can work around the problem by only configuring uplinks to your primary NNS/DLUS and backup NNS/DLUS, and use connection network for all other uplinks (vnname on port). Then snaswitch would only include 3 tail vectors in each locate (one to the primary, one to the backup, and one to the virtual routing node.)
