BayRS Version 15.5.0.0 Document Change Notice

5-6 314470-15.5 Rev 00

Beginning with this QoS enhancement, the Differentiated Services Code Point

(DSCP) tags (markings) assigned to BayRS router protocols are changed so that

packets originating from the router are marked with the Differentiated Services

Code Points shown in Table 5-2

. These markings are not configurable; they are

hard-coded and cannot be changed.

Note: Telnet server packets originating from the router in response to a Telnet

client connection have the same DSCP tag as packets from the incoming

Telnet connection. Telnet client packets originating from the router as a result

of a router initiated Telnet connection remain unaffected; thus, they have a

default tag of zero, which corresponds to the standard service class.
