Syslog traps

Does anyone know if there is a way to have more than 3 syslog destinations on a Cisco device. It is my understanding that only the first 3 are used in a device config. Can wildcards be used or are there any other work arounds?

Thanks.

Re: Syslog traps

There is no limit. My RSM had 2 defined and I just addedd 3 more:

nms-5500a-rsm#show logg

Syslog logging: enabled (0 messages dropped, 6 messages rate-limited, 0 flushes, 0 overruns)

Console logging: level debugging, 12744 messages logged

Monitor logging: level debugging, 0 messages logged

Buffer logging: level debugging, 12750 messages logged

Logging Exception size (4096 bytes)

Trap logging: level informational, 25449 message lines logged

Logging to 172.18.124.170, 25449 message lines logged

Logging to 172.18.123.49, 25449 message lines logged

Logging to 10.10.10.10, 1 message lines logged

Logging to 10.10.10.11, 1 message lines logged

Logging to 10.10.10.12, 1 message lines logged

Re: Syslog traps

Thanks.

Then it must be CATs only that have this limit. I just tried adding a new address and here is what I got: eccsedg1> (enable) set logging server 10.30.59.20

System logging server table is full. 10.30.59.20 not added into system logging server table.

This is a 6513 running 8.4.3.

Re: Syslog traps

CatOS has this limit.

There is no limit like this in IOS, so Cat switches running IOS would be OK with more than 3 syslog servers.

However, I generally discourage more than 4. There are obvious reasons for having more (lots of NM tools doing a lot of Syslog analysis), however, I'd start to investigate Syslog repeaters like Syslog-NG, if you really had that need.

You'd rather have a router/switch doing it's fundamental job rather than repeating a similar message over and over...

I worked with a customer that had 9 syslog receivers and 9 SNMP trap receivers. It was quite interesting seeing the message rate out of these boxes on Monday morning when all the users started up (Spanning Tree messages)...

Re: Syslog traps

That makes perfect sense to me.

Thank you.
