Distribution Layer April 2014

Connect the access layer EtherChannel uplinks to separate switches in the distribution layer Virtual Switching

System or stack.

Also, apply the egress QoS macro that was defined in the platform configuration procedure to ensure traffic is

prioritized appropriately.

Cisco Catalyst 4500 and 4500-X Series Switches do not use the logging event bundle-status command.

The Cisco Catalyst 6500 and 6800 Series Switches have two egress QoS macros:

EgressQoSOneGig, which is used for Gigabit Ethernet ports, and EgressQoS, which is

used for 10-Gigabit or 40-Gigabit Ethernet ports. All other distribution layer platforms

have a single egress QoS macro, which applies to all Ethernet ports, including Gigabit

Ethernet and 10-Gigabit Ethernet.

Tech Tip

Step 4: Configure the VLAN trunk interface to the access layer.

An 802.1Q trunk is used for the connection to the access layer, which allows the distribution switch to provide

Layer 3 services to all the VLANs defined on the access layer switch. Prune the VLANs on the trunk to only the

VLANs that are active on the access switch. When using EtherChannel the interface type will be port-channel

and the number must match the channel group configured in Step 3 .

The Cisco Catalyst 3750 Series Switch requires the switchport trunk encapsulation dot1q command.
