ISC Tagging Question

[troy_alan]

I accidentally untagged the ISC ports where we usually leave it tagged.  Should I expect this to give me any trouble?

As long as the VLAN membership matches on both sides of the link, it doesn't matter if any VLAN is untagged or not. The ISC VLAN should only be added to the ISC link that directly connects the 2 MLAG peers, but having it tagged or untagged doesn't really matter as long as the configuration matches on both sides.
