Re: UCX small buffer depletion

Forgive my ignorance, I have never had to devote this much attention to UCX and I am learning (more than I intended!). I didn't think I should be creating dynamic routes as dynamic routing is turned off. But if I "show comm/mem" I see small buffers used for routes increasing continually. And "sho com/rout" yields the following:

Route statistics

Created by redirects 1193
Modified by redirects 0
Wildcarded lookups 2484

Invalid redirect calls 73
Failed lookups 628
Maximum routes reached 0

So apparently I have not turned off dynamic routing, have I?

I have three static network routes defined, but one of them is 0.0.0.0. This was apparently added by one of our corporate "help desk" people when they and a contractor were reconfiguring the WAN router and LAN switches. I tried removing that network but then I could not connect to the VMS host (my PC is in a different class C). I think this is getting to the heart of the problem, they have not configured our local LAN switch correctly and we can not connect to the VMS host without going through the WAN router which I assume is where all the ICMP redirects are coming from.

Re: UCX small buffer depletion

the route to 0.0.0.0 is the the default route.

What does UCX SHOW ROUTE and SHOW ROUTE /PERM
say?

It does sound like your permenant routes need fixinf.

Re: UCX small buffer depletion

"sho rout" shows 4 routes, one class c, one class B, the default 0.0.0.0, and the host 127.0.0.1

"sho rout/perm" shows only the default of 0.0.0.0

Re: UCX small buffer depletion

$ UCX SHOW CONFIG START ROUTING
should tell you if dynamic routing is
enabled.

Re: UCX small buffer depletion

Dynamic routing is disabled.

$ ucx sho config start routing
%UCX-E-CONFIGERROR, Error processing CONFIGURATION request
-RMS-E-RNF, record not found

(My go-to-guy at corporate had just told me how to check that)

Re: UCX small buffer depletion

It appears that UCX is paying attention to redirects even though dynamic routing is off.
Do you know the routers you should be using?
Parhaps the default route should refer to the WAN router and then add specific routes for other subnets on the LAN?

You can add and remove routes in
UCX using the SET ROUTE command without restarting things then add them permenantly (so they get remembered) using SET ROUTE/PERM
