Description This parameter is based on the Type of Service (ToS), Differentiated
Services Code Point (DSCP) setting for SIP (tos sip parameter), RTP (tos
rtp parameter) and RTCP (tos rtcp parameter). It is the mapping between
the DSCP value and the VLAN priority value for SIP, RTP, and RTCP
packets.
You enter the tos priority map value as follows:
(DSCP_1,Priority_1)(DSCP_2,Priority_2).....(DSCP_64,Priority_64)
where the DSCP value range is 0-63 and the priority range is 0-7.
Mappings not enclosed in parentheses and separated with a comma, or
with values outside the ranges, are ignored.
Format Integer
Default Value 3 (based on the default ToS DSCP SIP setting of 26)
5 (based on the default ToS DSCP RTP setting of 46)
5 (based on the default ToS DSCP RTCP setting of 46)
Range 0 to 63 (for DSCP)
0 to 7 (for SIP, RTP, and RTCP priorities)
