14. map command
For a IP packet, there is priority information in ToS field of IP header. The
priority could be 3-bit precedence (0~7) or 6-bit DSCP (0~63).
For DSCP, this switch supports seven DSCP values for QoS operation and
other values will be assigned to one priority.
This command is used to map 802.1P priority values and DSCP priority values
to priority queues on the interface port(s). There are four priority queues for
each port. They are Low, Normal, Medium, and High priority queues. This
command can map the priority values to the four priority queues.
map ip dscp x y z command is used to map DSCP values to priority queues.
“x” is the index of the DSCP values and it could be 0-6 and “other”. “y” is the
DSCP value, and its valid value is 0-63. “z” is the prirority queue, and its value
is 0-3 (0:Low,1:Normal,2:Medium,3:High).
map ip precedence x y command is used to map 802.1P priority values to
priority queues. “x” is the value of IP Precedence in ToS, and its valid value is
0-7. “y” is the prirority queue and its value is 0-3 (0:Low, 1:Normal, 2:Medium,
3:High).
15. maximum-packet-length command
This command is used to set the maximum packet size allowed on the interface
port(s). For normal Etherent packets, the packet size is 64~1514 bytes. For
some gigabit connections, “jumbo frame” is allowed for higher data transfering
efficiency. This switch supports up to 9600 bytes packet size.
(config-if)# maximum-packet-length ?
1518 max. packet length=1518
1532 max. packet length=1532
9216 max. packet length=9216
9600 max. packet length=9600
16. no command
This command is used to disable a function or restore a setting to factory
default of the switch.
