The ports have been configured the same, but when something seems too simple, sometimes you begin to overthink things. Again, this change should be as if there was a momentary loss of network at L2 and reestablish itself once restored. However, with impacting many critical systems, I wanted to double check things before moving cables.</P> Wed, 26 Jul 2023 11:38:51 GMT https://community.cisco.com/t5/ip-telephony-and-phones/moving-c220-from-one-l2-device-to-a-new-l2-device/m-p/4892805#M411046 paullepper 2023-07-26T11:38:51Z https://community.cisco.com/t5/ip-telephony-and-phones/moving-c220-from-one-l2-device-to-a-new-l2-device/m-p/4892835#M411047 <P>If you get the config on your new switch / router straight, there is nothing to overthink.<BR />During the change, if you use multiple physical ports / adapters for redundancy in the ESXi, then you can switch port after port and see if you have reachability.<BR />But before the change, there isn't really something to check, other then making big stunts for such a low outcome check.</P> Wed, 26 Jul 2023 12:01:16 GMT https://community.cisco.com/t5/ip-telephony-and-phones/moving-c220-from-one-l2-device-to-a-new-l2-device/m-p/4892835#M411047 b.winter 2023-07-26T12:01:16Z https://community.cisco.com/t5/ip-telephony-and-phones/moving-c220-from-one-l2-device-to-a-new-l2-device/m-p/4892837#M411048 <P>Thanks for the assistance.</P> Wed, 26 Jul 2023 12:04:41 GMT https://community.cisco.com/t5/ip-telephony-and-phones/moving-c220-from-one-l2-device-to-a-new-l2-device/m-p/4892837#M411048 paullepper 2023-07-26T12:04:41Z
