packet is TCP or UDP.
Example
Console#show qos map ip-port-dscp interface ethernet 1/5
Information of Eth 1/5
ip-port-dscp map:
(ip protocol,destination port) : phb drop precedence
-----------------------------------------------------------
(TCP, 21) : 0 0
(UDP, 12) : 1 0
Console#
show qos map
ip-prec-dscp
This command shows the ingress IP precedence to internal DSCP map.
Syntax
show qos map ip-prec-dscp interface interface
interface
ethernet unit/port
unit - Stack unit. (Range: 1)
port - Port number. (Range: 1-28)
port-channel channel-id (Range: 1-26)
Command Mode
Privileged Exec
Command Usage
If the QoS mapping mode is set to IP Precedence and the ingress packet type is
IPv4, then the IP Precedence-to-DSCP mapping table is used to generate per-hop
behavior and drop precedence values for internal processing.
Example
Console#show qos map ip-prec-dscp interface ethernet 1/5
Information of Eth 1/5
IP-prec-DSCP map:
IP-prec: 0 1 2 3 4 5 6 7
------------------------------------------------------------
PHB: 0 1 2 3 4 5 6 7
drop precedence: 0 0 0 0 0 0 0 0
