Arista 7170-64c 202205 Port 65 and 66

[jimthedj65]

Hi Guys,

We have loaded 202205 onto our switch, and we can see mgmt eth0, loopback and with all ethernet 1 through to 64 ports which are able to come up and shutdown ok.

We can't seem to list the SFP ports 65 and 66 is there a config change to bring those ports up as ethernet ports on the 7170-64c

any help is appreciated in pointing us in the right direction to enable the two SFP ports on the 7170-64c

I was able to liost my 2 x 10 GBe interfaces as backplane devices. where would I configure these ports to be available in Sonic 202205.

I added the ports to /etc/sonic/config_db.json
"Ethernet256": {
"lanes": "256,257,258,259",
"alias": "Ethernet65/1",
"speed": "100000",
"index": "65",
"admin_status": "up",
"mtu": "9100"
}
},

"Ethernet260": {
"lanes": "260,261,262,263",
"alias": "Ethernet66/1",
"speed": "100000",
"index": "66",
"admin_status": "up",
"mtu": "9100"
}
},
restarted and they showed up but they have N/A under OPER and under Admin is showing UP

I have tried config interface Ethernet256 startup with no change on the interface.
Anyone caring to chip in appreciate it.

This was resolved with adding proper lanes to the config and rebooting 10Gig SFP need only 1 lane on the device as opposed to 100G needing 4 lanes.

I added the ports to /etc/sonic/config_db.json
"Ethernet256": {
"lanes": "256",
"alias": "Ethernet65/1",
"speed": "100000",

},

"Ethernet257": {
"lanes": "257",
"alias": "Ethernet66/1",
"speed": "100000",
"index": "66",
"admin_status": "up",
"mtu": "9100"
