Signaling Server can't find Call Server

[Arriero]

Hello,

I am having issues communicating the Sig Server to the Call Server.

- Ping from SS ELAN to Call Server ELAN does not respond
- Ping from my laptop (on ELAN) to SS ELAN is successful
- Ping from my laptop (on ELAN) to CS ELAN is successful

When I look at the route table on my Signaling Server I get the following information:

oam> routeShow

0.0.0.0 192.168.1.1 33619971 1 0 fei1

127.0.0.1 127.0.0.1 35651589 1 2 lo0
----------------------------------------------------------------------------

My ELAN is 47.1.1.0/24 and TLAN is 192.168.1.0/24
SS ELAN is 47.1.1.20 and SS TLAN is 192.168.1.5

System is CS1000M-MG R5.5

Any ideas on why do I have this 10.2.16.233 address in my SS route host table?

Thanks

the 10.2.16.233 may be your laptop.

Make sure you have a default route in your Call Server.

In LD 117 you should have something like

ld 117
OAM000

=> prt rout
Call Server 
 ID  Network          Gateway   
  1  0.0.0.0          172.21.102.254   
  2  172.21.102.0     172.21.102.11

In this example, my CallServer is 172.21.102.11, my default gateway is 172.21.102.254. and I use a 24-bit mask (255.255.255.0)

So anything not in 172.21.102.0 will be sent to the default gateway, and anything in 172.21.102.0 will be sent out through the E-LAN interface.

Hmmm... There all on the same subnet... so route does not matter. If what your telling us is correct I would look at a possible bad Ethernet Switch port/s. It should not be behaving as you stated above.

Can you ping the SS E-LAN from the Call Server? I didn't see if you had tried this from the original post.

It definitely sounds like it could be network related as you can ping both e-lan interfaces from a third device.

Anyway, here are the route tables from 2 of my leader signaling servers for comparison - maybe it will be helpful:

Allenmac, thanks for your feedback. The Call Server IP info looks as follows:

>ld 117
OAM000

=> prt host
ID Hostname IP Address
1 CS_PRIM 47.1.1.11
2 CS_SEC 47.1.1.12

=> stat host
*** Active Internet Host Table ***
ID Hostname IP Address
-- localhost 127.0.0.1
1 CS_PRIM 47.1.1.11
2 CS_SEC 47.1.1.12

=>
AUD000
prt rout
ID Network Gateway
2 0.0.0.0 47.1.1.1
OK

=> stat rout

*** Active Route Net Table ***
ID Network Gateway
-- 0.0.0.2 47.1.1.11
-- 35.35.40.0 35.35.40.1
-- 35.35.40.128 35.35.40.129
-- 35.35.41.0 35.35.41.1
-- 35.35.41.128 35.35.41.129
-- 127.0.0.0 127.2.0.2

*** Active Route Host Table ***
ID Network Gateway
-- 127.0.0.1 127.0.0.1

I connected my laptop on 47.1.1.190 and from there I can ping SS-ELAN and CS-ELAN, however CS-ELAN doesn't see SS-ELAN and vice versa... that is what puzzles me.

I am still intrigued with the 10.2.16.233 address... don't have a clue where it may come from.

On your active route table, the first entry is 0.0.0.2 - shouldn't that be 0.0.0.0?

It looks like you need to enable rout 2 - in LD 117 the command is: enl rout 2.
