Predefined Protocol Filters
The following protocol filters are predefined on the switch:
• IP (IPv4)
• IPv6 (11.2 IPv6)
• IPX
• NetBIOS
• DECNet
• IPX_8022
• IPX_SNAP
• AppleTalk
Defining Protocol Filters
If necessary, you can define a customized protocol filter by specifying EtherType, Logical
Link Control (LLC), or Subnetwork Access Protocol (SNAP). Up to six protocols can be part
of a protocol filter. To define a protocol filter:
1. Create a protocol using the following command:
create protocol <name>
For example:
create protocol fred
The protocol name can have a maximum of 32 characters.
2. Configure the protocol using the following command:
configure protocol <name> add [etype | llc | snap] <hex> {[etype | llc | snap] <hex>}
Supported protocol types include:
• etype—EtherType
The values for etype are four-digit hexadecimal numbers taken from a list maintained
by the IEEE. This list can be found at the following URL:
http://standards.ieee.org/regauth/ethertype/index.html
• llc—LLC Service Advertising Protocol (SAP)
The values for llc are four-digit hexadecimal numbers that are created by
concatenating a two-digit LLC Destination SAP (DSAP) and a two-digit LLC Source
SAP (SSAP).
• snap—Ethertype inside an IEEE SNAP packet encapsulation
The values for snap are the same as the values for etype, described previously.
For example:
configure protocol fred add llc feff
configure protocol fred add snap 9999
