System Messages --

You can now have the router send system logging messages (sometimes refered to syslog,
after the Unix Process ) to another device in an XML format. This theoretically allows for fancy front ends
or GUIs which would allow you to look at logs for all of the devices on the
network (routers send logs to a host/client/management station while a Windows/Unix/
Linux program retreives and displays them for you).

See "XML Interface to Syslog Messages" [Oct. 2004].
If the doc isn't clear, please send feedback using the form on the left of the screen.

For system logging fundamentals, see the Cisco IOS Configuration Fundamentals book
for Cisco IOS Release 12.3 or Cisco IOS Release 12.4 .


Service Level Agreements for IP -based network infrastructures (IP SLAs); integrated monitoring options for Service Providers --

Despite the stupid name choice for this Cisco IOS Software feature
("IP SLAs"; the same name used for the actual agreements between services providers and users) Cisco IOS software-based routers have this built-in network monitoring tool which is actually pretty cool.
Since it's built in, you don't have to necessarily get external tools or devices to see how the network
is performing (unless you want the GUI). There's also a market that allows you to make a
GUI to get collected data from the 'IP SLAs monitoring tool' via SNMP, present it all prettified,
and sell your ADVANCED NETWORK MANAGEMENT UTILITY for a million bucks....
[update: the 12.4 Documentation is now available]

Read about the Cisco Systems' IP SLA Monitor (aka Cisco IOS IP SLAs, formerly the Service Assurance Agent [SAA/ SA Agent], formerly the Response Time Reporter [RTR]) here. It's come a long way since it's birth as the "Round Trip Time Monitor" way back about 5 major
releases ago... (thought the MIB is still called that).


Hi Gale-

I was on vacation when these emails were going back and forth: sorry for the delay in getting back to you.
Here is the info you need for the doc:

1. RTR indicates the “Service Assurance Agent” (SAA) feature.

2. SAA documentation is now separated from the other Network Management/Configuration Fundamentals docs, see

3. RTR originally meant “Response Time Reporter”, but that name was replaced in the code by “Service Assurance Agent”.

For example:

    Router(config)# rtr 1
    Router(config-rtr)# ?
     SAA Entry Configuration Mode commands:
     . . .
    Router (config-rtr)# _

4. please see the following documents as important references about the SAA SLM feature:
 (SLM = service level monitor)

5. rtr commands are replaced in 12.3(14)T and later by IP SLA commands. See

Hope that helps!

Cisco IOS Release 12.2S

July 25 2005 - The next major release of 12.2S is 12.2(30)S (a.k.a Release 6 of 12.2S).
This release will be, for mysterious reasons, for the ONS platform only. For customers waiting on new features who are running other platforms, Cisco is recommending other release trains, such as 12.2SB, 12.2SBC, 12.2SX, and other confusingly identified releases.
12.2.S-30 features (12.2.30.S / 12.2(30)S):
"Exclusive Configuration Change Access (Configuration Lock) and Access Session Locking"
/ "Exclusive Configuration Change Access" (frid=13159)
