Hello All,<br><br>Recommend not upgrading to 6.2 if you use ISC. <br>Found that once upgraded, ISC will take out all lines of &#39;switchport trunk allowed vlan&#39; except the first when deploying new services.<br><br>Ex, when trying to add vlan 3000<br>

<br>switchport trunk allowed vlan 1-3, 6-8, 78-82 99-199<br>switchport trunk allowed vlan add 1125,1129-1335,2025<br><br>becomes<br><br>
switchport trunk allowed vlan 1-3, 6-8, 78-82 99-199,3000<br><br>Somewhat disquieting. Already rolled back to 6.1.4 as that could happily take out a core network.<br><br>Regards,<br><br>Alex.<br>
