HP Moonshot Switch Module CLI Command Reference
match ip precedence
This command adds to the specified class definition a match condition based on the value of the IP Precedence
field in a packet, which is defined as the high-order three bits of the Service Type octet in the IP header (the
low-order five bits are not checked). The precedence value is an integer from 0 to 7.
match ip tos
This command adds to the specified class definition a match condition based on the value of the IP TOS field in
a packet, which is defined as all eight bits of the Service Type octet in the IP header. The value of
tosbits is a
two-digit hexadecimal number from 00 to ff. The value of
tosmask is a two-digit hexadecimal number from 00
to ff. The
tosmask denotes the bit positions in tosbits that are used for comparison against the IP TOS field in
a packet. For example, to check for an IP TOS value having bits 7 and 5 set and bit 1 clear, where bit 7 is most
significant, use a
tosbits value of a0 (hex) and a tosmask of a2 (hex).
match protocol
This command adds to the specified class definition a match condition based on the value of the IP Protocol
field in a packet using a single keyword notation or a numeric value notation.
To specify the match condition using a single keyword notation, the value for protocol-name is one of the
supported protocol name keywords. The currently supported values are:
icmp, igmp, ip, tcp, udp. A value of ip
matches all protocol number values.
To specify the match condition using a numeric value notation, the protocol number is a standard value
assigned by IANA and is interpreted as an integer from 0 to 255.
Note: The IP DSCP, IP Precedence, and IP ToS match conditions are alternative ways to specify a match
criterion for the same Service Type field in the IP header, but with a slightly different user notation.
Default none
Format
match ip precedence 0-7
Mode Class-Map Config
Note: The IP DSCP, IP Precedence, and IP ToS match conditions are alternative ways to specify a match
criterion for the same Service Type field in the IP header, but with a slightly different user notation.
Note: This “free form” version of the IP DSCP/Precedence/TOS match specification gives the user
complete control when specifying which bits of the IP Service Type field are checked.
Default none
