Configuring Traffic Filters and Protocol Prioritization

8-14

308645-14.00 Rev 00

If you specify a protocol other than TCP or UDP, the software prevents you from

filtering on the TCP or UDP source or destination. Otherwise, the offset

associated with one of the parameters in the non-UDP/TCP packet could

coincidentally match the filter, and the software would perform the filter’s action.

To filter traffic using the protocol field, navigate to the match prompt (for

example,

box; ip; filter-template/telnet-in; match) and enter the following

command:

protocol {<

list_of_protocols>

}

list_of_protocols

can include any number of protocol identifiers. It can also

specify ranges of protocol identifiers.

Table 8-4

lists some common protocol ID codes for IP traffic.

Example

To match IGP packets, enter the following command:

match/template/template1# protocol 9

match/template/template1#

Table 8-4. Common Protocol IDs for IP Traffic

Protocol ID Code (Decimal)

ICMP (Internet Control Message Protocol) 1

IGMP (Internet Group Management Protocol) 2

TCP (Transmission Control Protocol) 6

EGP (Exterior Gateway Protocol) 8

IGP (Interior Gateway Protocol) 9

UDP (User Datagram Protocol) 17

RSVP (Resource Reservation Protocol) 46

GRE (Generic Routing Encapsulation) 47

NHRP (Next Hop Resolution Protocol) 54

OSPF (Open Shortest Path First) 89
