Still waiting for 100G breakout cables, but I got 2*10G ports working now.
1. Initial configuration is completed for switch itself. NTP server is configured in the switch,
2. fan speed is now set to 35% and I'm very happy with the result.
3. LACP port channel is created between Arista and ICX 7250.
4. All the vlans are configured and trunked, and IP addresses are migrated from ICX 7250. DHCP relay is also configured.
5. iBGP is now set up between Arista and Juniper SRX firewall. It will be used for Kunernetes Calico BGP routing a bit later.
I'm not a network guy, especially on routing. This is the first time I play with BGP and it's working after some tweaks, not as complicated as what I thought.
