Cisco IOS Router and Switch

Issue with Generic Serial Numbers in Older Versions of Cisco IOS Routers

FortiSIEM uses serial numbers to uniquely identify a device. For older routers, the serial number is obtained from the OID 1.3.6.1.4.1.9.3.6.3.0. However, this value is often incorrectly set by default to a generic value like MSFC 2A. If multiple routers have a common default value, then these routers will be merged into a single entry in the FortiSIEM CMDB.

You can check the current value for the serial number in a Cisco router by doing a SNMP walk of the OID.

snmpwalk -v2c -c <cred> <ip> 1.3.6.1.4.1.9.3.6.3.0

If the value is a generic value, then set it to the actual serial number.

Router(config)#snmp-server chassis-id
 Router(config)#exit 
 Router#write memory

Run the snmpwalk again to verify that the serial number is updated, then perform discovery of your Cisco router.

IP SLA

IP SLA is a technology where a pair of routers can run synthetic tests between themselves and report detailed traffic statistics. This enables network administrators to get performance reports between sites without depending on end-host instrumentation.

Cisco provides detailed documents for configuring IP SLA for both general traffic and VoIP.

A variety of IP SLA tests can be run, for example UDP/ICMP Jitter, UDP Jitter for VoIP, UDP/ICMP Echo, TCP Connect, HTTP, etc. You can see the traffic statistics for these these tests by routing appropriate Show commands on the router. However, only these IP SLA tests are exported via RTT-MON SNMP MIB.

  • UDP Jitter (reported by FortiSIEM event type PH_DEV_MON_IPSLA_MET)
  • UDP Jitter for VoIP (reported by FortiSIEM event type PH_DEV_MON_IPSLA_VOIP_MET)
  • HTTP performance (reported by FortiSIEM event type PH_DEV_MON_IPSLA_HTTP_MET)
  • ICMP Echo (reported by FortiSIEM event type PH_DEV_MON_IPSLA_ICMP_MET)
  • UDP Echo (reported by FortiSIEM event type PH_DEV_MON_IPSLA_UDP_MET)

These are the only IP SLA tests monitored by FortiSIEM.

Configuring IP SLA involves choosing and configuring a router to initiate the test and a router to respond. The test statistics are automatically reported by the initiating router via SNMP, so no additional configuration is required. Bi-directional traffic statistics are also reported by the initiating router, so you don't need to set up a reverse test between the original initiating and responding routers. FortiSIEM automatically detects the presence of the IP SLA SNMP MIB (CISCO-RTTMON-MIB) and starts collecting the statistics.
