Monitoring Devices in In-Band Network
Perform the following task to monitor devices in the In-band network.
Procedure
Step 1 |
Deploy Cisco DCNM in Standalone mode or Native HA mode. For more information, see Installing the Cisco DCNM. |
||
Step 2 |
Configure In-band route on the DCNM server using the command: appmgr setup inband-route subnet {fabric-links-subnet/mask | loopback-IP-subnet/mask} where,
On switches, User may configure the same loopback Interface (like loopback x) and choose its IP address in a subnet with /32 mask or as appropriate for their network and while installing the DCNM server (s) also use the eth2 IPs and in native-ha bring up eth2 VIP IP also in same IP subnet as that of switch loopback IP subnet. On Servers, User can use a summarized group mask (eg: /24 in this example) so that only a few static routes on the server are needed
Now ping from server to switch loopback IP or switch to the server (via vrf default) both ways ping should go through fine |
||
Step 3 |
Ping the switch loopback IP address from the DCNM server, or ping the server (via default vrf) to the switch. Ensure that you can ping both the routes successfully. |
||
Step 4 |
Logon to the Cisco DCNM server. Navigate to the /usr/local/cisco/dcm/fm/conf directory. |
||
Step 5 |
Edit the trap registry values in the server.properties file. Set the traps.registaddress=eth2-VIP-IPAddress Save the server.properties file. |
||
Step 6 |
Restart the Cisco DCNM using the following commands: appmgr stop all appmgr start all
|
||
Step 7 |
On Cisco DCNM Web UI, discover the devices, based on loopback IP addresses of the Switch. Ensure that the discovery occurred through the server to the switch using inband connectivity |
||
Step 8 |
Edit the pmn_telemetry_snmp template and provide appropriate details.
|
||
Step 9 |
Deploy the modified configuration to the switch. |
