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, congure VLAN tags on a Layer 3 port
interface which is congured with an IP address but has no VLAN associated with it. You can also congure a VLAN sub-interface on
the port interface and apply a policy map that classies 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 conguration mode.
To apply a Layer 2 policy on a Layer 3 interface:
1. Congure an interface with an IP address or a VLAN sub-interface
CONFIGURATION mode
Dell(conf)# interface fo 1/4
INTERFACE mode
Dell(conf-if-fo-1/4)# ip address 90.1.1.1/16
2. Congure 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-1/4)# service-policy input l2p layer2
Managing Hardware Buer Statistics
Bufer statistics tracking utility is supported on the 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 buer 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 buer that is utilized by a queue. This dynamic partition or block is set to
be two-thirds of the available buers for all unicast queues and one-fth of the available buers for all multicast queues on these
platforms.
