ITS has scheduled the following maintenance:
What: Power cycle line cards of b-core router
When: Thursday 4/8/2021 from 9 PM to 11 PM
ITS network team will power cycle the line cards of b-core router. Errors are being generated by the card and the vendor recommends power cycling or reseating it then verify the errors ceased.
Network with alternate path won't be affected as we will power cycle the cards one at a time but might experience brief packet loss. Network without redundancy will have an outage for about 10-15 minutes while the card is rebooting. Any VLAN which spans vlan through the b-core will also be affected.
Connections with redundant or alternate path
Below are the buildings with single path and with vlan spanned and will experience an outage:
vlan 6 [muir]ad-test-forest
vlan 201 [m]hds-srvr-ext-inside
vlan 337 [b]pps-vlan
vlan 2856 [s]s-ogs-srvr-int-inside
vlan 2858 [s]s-ogs-srvr-ext-inside
vlan 3444 [its-colo]ucsd-ats-ogs-inside
vlan spanned through the core from ADCOM.
