The switch is not performing routing functions on a VLAN

Two possible causes of this problem are:

  • Routing is not enabled.

  • An ACL may be blocking access to the VLAN (on a switch covered in this guide). Ensure that the switch's IP address on the VLAN is not blocked by one of the ACE entries in an ACL applied to that VLAN. A common mistake is to either not explicitly permit the switch's IP address as a DA or to use a wildcard ACL mask in a deny statement that happens to include the switch's IP address. For an Example: of this problem, see section "General ACL Operating Notes" in the "Access Control Lists (ACLs)" of the latest access security guide for your switch.
