Configure Inband Connectivity for Fabric Upgrade
How to Configure Inband Connectivity for Fabric Upgrade
This use case guides you in configuring your network for Inband connectivity when used in conjunction with Fabric Upgrade (or downgrades).
Please review the Arista Networks' recommended procedure for more information before upgrading or downgrading a Fabric.
Switch Inband Configuration
On each switch in the Fabric run the following commands from the CLI (Command Line Interface):
|
switch-route-create network <eth2 network of UNUM> gateway-ip <fabric-nic interface IP> switch-route-show |
For example:
|
CLI (network-admin@aries-unum-spine1) > switch-route-create network 10.1.0.0/16 gateway-ip 10.1.2.1 |
NetVisor UNUM Inband Configuration
On your NetVisor UNUM VM (Virtual Machine) instance and from the the Linux command shell run the following commands:
|
route add -net <switch inband network> gw <UNUM gw IP for eth2> netstat -rn |
For example:
|
vcf@unum:~$ sudo route add -host 10.110.0.1 dev eth2 vcf@unum:~$ sudo route add -net 10.1.2.1 netmask 255.255.255.240 gw 10.110.0.1 dev eth2 netstat -rn |
Option - Modify Interfaces Configuration File
Edit the interfaces configuration file from the the Linux command shell using the following commands:
|
up route add -net <switch inband network> gw <UNUM gw IP for eth2> dev eth2 or eth2.<vlantag> |
For example:
|
sudo nano /etc/network/interfaces up route add -net 10.1.2.1 netmask 255.255.255.240 gw 10.110.0.1 eth2 |
