Feature InformationReleasesFeature Name
The TCP Explicit Congestion
Notification (ECN) feature allows
an intermediate router to notify end
hosts of impending network
congestion. It also provides
enhanced support for TCP sessions
associated with applications such
as Telnet, web browsing, and
transfer of audio and video data,
that are sensitive to delay or packet
loss. The benefit of this is the
reduction of delay and packet loss
in data transmissions.
The following commands were
introduced or modified by this
feature: debug ip tcp ecn, ip tcp
ecn, show debugging, show tcp.
12.3(7)TTCP Explicit Congestion
Notification
The TCP MIB for RFC 4022
Support feature introduces support
for RFC 4022, Management
Information Base for the
Transmission Control Protocol
(TCP). RFC 4022 is an incremental
change of the TCP MIB to improve
the manageability of TCP.
There are no new or modified
commands for this feature.
