Similar to T295691, T295690, T316529. The Junos 21 branch is now in Junos recommended versions for our access switches, see https://kb.juniper.net/InfoCenter/index?page=content&id=KB21476&smlogin=true Upgrading them brings several advantages: * Keeping a tight Junos version spread (we currently have 14, 17, 18, 20) * Leveraging features improvements (eg. DNS in mgmt-junos see T269340) * Fixing low risk security issues Those switches are `L2` only, so it's less urgent as they're not exposed to the Internet, and they're in VCs so it means all members have to go down at the same time (we're not trying ISSU and similar). |Device|Scheduled for|Status| |---|---|---| |asw1-eqsin| Jan 9th - 10:00UTC | | |asw2-ulsfo| Jan 11th - 10:00UTC | | |asw2-esams| Jan 12th - 10:00UTC | |
