Encountering an issue when trying to bond two nics in a HP server running 22.04.

I'm using the following netplan config file and two ports on the cisco switch bonded with LACP, the ports on the cisco switch come up as suspended when bond0 is brought up.

network:

  version: 2

  renderer: networkd
  ethernets:

    eno1:
      dhcp4: false
    eno2:
      dhcp4: false
    eno3:
      dhcp4: false
      addresses:
        - 172.18.16.1/24
      nameservers:
        addresses: [172.18.10.250, 172.18.10.251]
      routes:
        - to: default
          via: 172.18.16.254
    eno4:
      dhcp4: true
    eno49:
      dhcp4: true
    eno50:

Welcome to AskUbuntu! Your question is unclear of how this deals with Ubuntu and what version you are using. Also, your information that you have posted is not exact. Please make sure that when you post code information from a file that it is formatted correctly. Make sure to test your config as well. See: https://manpages.ubuntu.com/manpages/jammy/man8/netplan-try.8.html Also make sure that your switch is configured properly to support LACP and that you have no failures of the bond configured.

I'm using mostly the same config for creating a bond myself to a UniFi Switch - the only difference is I don't have the `mii-monitor-interval: 1` line - and this works fine for me. Are you sure the ports are configured as aggregate on the Cisco Switch as well?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
