Chapter 52 Configuring QoS
Understanding How QoS Works
IP ACE Layer 4 IGMP Classification Criteria
You can create the IGMP ACEs that match the traffic containing the specific IGMP messages by
including an IGMP type parameter (for more information, see the “IP ACEs for IGMP Traffic” section
on page 52-49). You can specify the IGMP type numerically (0–255) or with these keywords:
host-query (1), host-report (2), dvmrp (3), pim (4), or trace (5).
Note • QoS supports multicast traffic when IGMP snooping is enabled.
• QoS does not support the IGMP traffic when IGMP snooping is enabled.
• QoS supports IGMP classification using version 1 four-bit Type fields.
• The IGMP ACEs that do not include a Layer 4 IGMP type parameter match all IGMP traffic.
IPX ACE Classification Criteria
Note PFC3 does not provide QoS for the IPX traffic. See the “MAC ACE Layer 2 Classification Criteria”
section on page 52-21 for information about how to use MAC ACLs to filter IPX traffic.
You can create the IPX ACEs that match the specific IPX traffic by including these parameters (for more
information, see the “Creating or Modifying the Named IPX ACLs” section on page 52-51):
• IPX source network (-1 matches any network number)
• Protocol, which can be specified numerically (0–255) or with these keywords: any, ncp (17),
netbios (20), rip (1), sap (4), spx (5)
• IPX ACEs support the following optional parameters:
– IPX destination network (-1 matches any network number)
– If you specify an IPX destination network, the IPX ACEs support the following optional
parameters: an IPX destination network mask (-1 matches any network number), an IPX
destination node, and an IPX destination node mask
MAC ACE Layer 2 Classification Criteria
You can create the MAC ACEs that match the specific Ethernet traffic by including these Layer 2
parameters (for more information, see the “Creating or Modifying the Named MAC ACLs” section on
page 52-53):
• Ethernet source and destination addresses and masks, entered as specific values or with the any
keyword or with the host keyword and a host Ethernet address
• Optionally, an EtherType parameter from this list:
– 0x809B (or ethertalk)
– 0x80F3 (or aarp)
– 0x6001 (or dec-mop-dump)
– 0x6002 (or dec-mop-remote-console)
– 0x6003 (or dec-phase-iv)
– 0x6004 (or dec-lat)
