FW: Stupid Question [7:32591]

[Aki Christopoulos]

INTERESTING,

The 6509 Switches have the option of having NAM (Network Analysis
Module) and IDS (Intrusion detection system) cards.
(i.e. 6509- Switch, Router, NMS, IDS etc. on one box) 

>From Cisco's Web site

"An illuminated hard drive activity LED indicates that the hard drive is
in use."

"To prevent corruption of the NAM, it is critical that the NAM run
through the shutdown procedure before shutting off. If the NAM fails to
respond to CLI or NAM shutdown commands, you can use the Shutdown button
as an alternative shutdown method. "
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/6000hw/mod_i
nst/01overvw.htm#xtocid2525837

(Hard drive ?? What OS/IOS would require a hard drive... (The mind does
wonder ;-) )

You cannot JUST POWER OFF SOME SWITCHES...
It all depends what switching platform you have, and what options you
have installed...

Hope this helps,

Aki

Just turn them off or simply unplug them.  

Fortunately the IOS was not written by Microsoft and nothing will get
corrupted!!!

VoIP, STAC and cRTP problems ?? [7:6121]

[Aki Christopoulos]

Hi there,

PPP link can be configured with STAC/Predictor compression (Layer 2)

cRTP compression algorithm to compress UDP packets nameley for voice (layer
3)

The problem comes about, when you want to enable both, PPP STAC and cRTP on
the same interface. Cisco's IOS accepts both commands, but uses only PPP STAC
over cRTP.
(cRTP is enabled but does not function : Verified this by sho ip rtp
header-compression, and debug ip rtp header-compression)

Here is a sample config of the serial interface :

interface Serial0/0
 ip address 10.1.2.2 255.255.255.252
 encapsulation ppp
 ip tcp header-compression iphc-format
 no ip mroute-cache
 compress stac
 ip rtp header-compression iphc-format

Has anyone also had the same problem ??

THANKS IN ADVANCE

Aki Christopoulos

Route Poisoning and Poison Reverse?? [7:4666]

[Aki Christopoulos]

I understand that both (Route Poisoning and Poison reverse) are used with
Distance Vector Routing Protocols, but I am not able to get a clear
definition
of Route Poisoning..

What is the difference between the two??

Thanks in Advance

AKI
