Configuring Cisco 7500 series router
- Customer Success & Engineering (Unlicensed)
To configure the Cisco 7500 series to routers, below are the steps:
1. Enabling Netflows
To enable NetFlow, use the following commands beginning in global configuration mode:
| Command | Purpose |
Step 1 | Router(config)# interface type slot/port-adapter/port (Cisco 7500 series routers) Or Router(config)# interface type slot/port (Cisco 7200 series routers) | Specifies the interface, and enter interface configuration mode. |
Step 2 | Router(config-if)# ip route-cache flow | Enables NetFlow for IP routing. |
2. Exporting Netflows to the CCE:
The routers must be individually configured to forward Netflow information to the IP address of the CCE.
Follow these steps on each router:
Command | Purpose |
Router(config)# ip flow-export ip-address udp-port version 5 [origin-as | peer-as] | Configures the router to export NetFlow cache entries to a workstation if you are using receiving software that accepts version 5. Optionally specify the origin or peer autonomous system. The default is to export neither AS that provides improved performance. |
The CCE’s IP Address should be used in the above command and the udp port number is: 9995, The CCE supports both Version 5 and Version 9 and IPFIX.
The distinguishing feature of Netflow Version 9 is that it is template based. Seceon OTM needs the
IN_BYTES, IN_PKTS, PROTOCOL, SRC_TOS, TCP_FLAGS, L4_SRC_PORT, IPV4_SRC_ADDR, SRC_MASK, INPUT_SNMP, L4_DST_PORT, IPV4_DST_ADDR, DST_MASK, DST_MASK, OUTPUT_SNMP, IPV4_NEXT_HOP, LAST_SWITCHED, FIRST_SWITCHED, SRC_AS.

Example:
Router(config)# ip flow-export 192.168.419.44:9995 version 9 [origin-as | peer-as]
