Consultation in the company we have a router powered by 2 transceiver, main and secondary link to the router, as these transceivers do not have ip there is some way to monitor them? Some plug that helps with this work

I'm sure there's a device you could use, but I don't know what one to use off the top of my head.

Depending on your requirements, it may be easier to get that data from the router via SNMP. Something like https://www.cisco.com/c/en/us/support/d ... anges.html

If you tell us what make/model of router, we can probably be more helpful.

Cisco 2900 series on the back says cisco 2911

It appears as though there are a few plugins that may be able to get you what you want: https://library.nagios.com/library/tech ... equipment/

Please test one of those out and let us know any errors you receive.

Query, I will have to enable something on the router since when I make a query I get the following message

[root@localhost plugins]# ./check_env_stats.py -H 192.168.2.1 -M power -T cisco
Timeout: No Response from 192.168.2.1
Timeout: No Response from 192.168.2.1
Error: description / value table empty or non-existent.
[root@localhost plugins]#

When testing the router with another plugin I get the following message

[root@localhost plugins]# ./check_cisco_catalyst.pl -H 192.168.3.1 -C public -t int
SNMP error: No response from remote host "192.168.3.1"
[root@localhost plugins]# ./check_cisco_catalyst.pl -H 192.168.2.1 -C public -t int
SNMP error: No response from remote host "192.168.2.1"
[root@localhost plugins]# ./check_cisco_catalyst.pl -H 192.168.1.1 -C public -t int
SNMP error: No response from remote host "192.168.1.1"

When consulting another computer in this case a printer I have no problems

[root@localhost plugins]# snmpwalk -v 1 -c public -O e 192.168.2.170

Will I have to enable snmp on router?

Yes! And you will also need to set the community string to match what you are using in the command (in your example "public")

I will have to ask my internet provider to activate it since I do not have access to the router, thanks for the answer

I had an open thread but it is locked

answer I was going to leave in the post

Hello, now it is already active snmp, you could orientate with command line to be able to see active interfaces in the router the idea is to see if I can identify if one of the transceiver stops working like for example a cut in the optical fiber. I have put some commands and SNMP is working without problems

[root@localhost plugins]# ./check_cisco_catalyst.pl -H 192.168.2.1 -C YOLITO -t freeint
Free Interfaces: OK - 4/8 free interfaces for 14 days | total_int=12 total_eth=8 total_eth_free=4
[root@localhost plugins]# ./check_cisco_catalyst.pl -H 192.168.2.1 -C YOLITO -t int
UNKNOWN: does not exists | int=0
[root@localhost plugins]# ./check_env_stats.py -H 192.168.2.1 -C YOLITO -M power -T cisco
OK: C2911 AC Power Supply: 1, Redundant Power Supply: 5

thx.!

Thanks for following back up. I have merged this back into the original topic!
