Remove the access list from the interface. Choose
Switches > Security > IP ACL
in Fabric Manager, select
the

Delete the deny filter. Choose
Security > IP ACL
in
Device Manager, right-click the access list, and click
Rules
. Right-click the filter you want to delete and click

IP-ACL configuration submode.
Deny filter is too high in the access list
order.
Delete the access list and re-create. See the

IP-ACLs Using Fabric Manager” section on page 21-5

the

click
Rules

Create.
Or use the
ip access-list

permit
CLI command in IP-ACL
configuration submode.
