Applying Layer 2 Match Criteria on a Layer 3 Interface

To process Layer 3 packets that contain a dot1p (IEEE 802.1p) VLAN Layer 2 header, configure VLAN tags

on a Layer 3 port interface which is configured with an IP address but has no VLAN associated with it. You

can also configure a VLAN sub-interface on the port interface and apply a policy map that classifies

packets using the dot1p VLAN ID.

To apply an input policy map with Layer 2 match criteria to a Layer 3 port interface, use the service-

policy input policy-name layer 2

command in Interface configuration mode.

To apply a Layer 2 policy on a Layer 3 interface:

1. Configure an interface with an IP address or a VLAN sub-interface

CONFIGURATION mode

Dell(conf)# interface fo 0/0

INTERFACE mode

Dell(conf-if-fo-0/0)# ip address 90.1.1.1/16

2. Configure a Layer 2 QoS policy with Layer 2 (Dot1p or source MAC-based) match criteria.

CONFIGURATION mode

Dell(conf)# policy-map-input l2p layer2

3. Apply the Layer 2 policy on a Layer 3 interface.

INTERFACE mode

Dell(conf-if-fo-0/0)# service-policy input l2p layer2

Managing Hardware Buffer Statistics

Bufffer statistics tracking utility is supported on the S6000 platform.

The memory management unit (MMU) on S6000 platform is 12.2 MB in size. It contains approximately

60,000 cells, each of which is 208 bytes in size. MMU also has another portion of 3 MB allocated to it.

The entire MMU space is shared across a maximum of 104 logical ports to support the egress admission-

control functionality to implement scheduling and shaping on per-port and per-queue levels. Also, the

MMU buffer cells can be used by each port or queue either as a static partition or as a dynamic partition.

With dynamic mode, you can specify the percentage of available buffer that is utilized by a queue. This

dynamic partition or block is set to be two-thirds of the available buffers for all unicast queues and one-

fifth of the available buffers for all multicast queues on these platforms.
