Configuring Gigabit Ethernet Interfaces
Step 4 Do the following:
• Click Deploy Now to save your entries and to return to the Physical Interface table.
• Click Cancel to exit the procedure without saving your changes and to return to the Physical
Interface table.
• Click Next or Previous to go to the next or previous physical channel.
• Click Delete to remove this entry from the Physical Interface table and to return to the table.
Step 5 (Optional) To display statistics and status information for a particular Gigabit Ethernet interface, choose
the interface from the GigabitEthernet Interfaces table, and click Details.
The show interface gigabitEthernet CLI command output appears. See the “Displaying Gigabit
Ethernet Interface Statistics and Status Information” section on page 10-9 for details.

Carrier Delay Adds a configurable delay at the physical port level to address any issues with
transition time, based on the variety of peers. Valid values are 0 to 120
seconds. The default is 0 (no carrier delay).
Note If you connect an ACE to a Catalyst 6500 series switch, your
configuration on the Catalyst may include the Spanning-Tree
Protocol (STP). However, the ACE does not support STP. In this case,
you may find that the Layer 2 convergence time is much longer than
the physical port up time. For example, the physical port would
normally be up within 3 seconds, but STP moving to the forward state
may need approximately 30 seconds. During this transitional time,
although the ACE declares the port to be up, the traffic will not pass.
In this case, specify a carrier delay.
QoS Trust COS Enables Quality of Service (QoS) for the physical Ethernet port. By default,
QoS is disabled for each physical Ethernet port on the ACE.
QoS for a configured physical Ethernet port based on VLAN Classes of
Service (CoS) bits (priority bits that segment the traffic in eight different
classes of service). When you enable QoS on a port (a trusted port), traffic is
mapped into different ingress queues based on their VLAN CoS bits. If there
are no VLAN CoS bits, or QoS is not enabled on the port (untrusted port), the
traffic is then mapped into the lowest priority queue.
You can enable QoS for an Ethernet port configured for fault tolerance. In this
case, heartbeat packets are always tagged with COS bits set to 7 (a weight of
High).
Note We recommend that you enable QoS on the FT VLAN port to provide
higher priority for FT traffic.
