Unable to send ip routing table events to ssh session in Comware 7.

[Andyo]

Hello everybody!

As I read in the manual, the following steps must enable ip routing table events (such as insertion of perfix or deletion prefix) while ssh'ing in the Comware 7 device:

<device> terminal debugging

<device> terminal logging

<device> terminal monitor

<device> debugging ip address event

then to verify:

[device] display debugging
 IP address event debugging switch is on
[device ]display info-center
Information Center: Enabled
Console: Enabled
Monitor: Enabled
Log host: Enabled
Log buffer: Enabled
    Max buffer size 1024, current buffer size 512
    Current messages 169, dropped messages 0, overwritten messages 0
Log file: Enabled
Security log file: Disabled
Information timestamp format:
    Log host: Date
    Other output destination: Date

But when I manipulate by the routing table (by remotely inserting/deleting routes) I cannot see any messages in the session. Do anybody help me with this?

Thank U in advance

Hi,

Several things here.

1:

If its comware 7, the command "terminal logging" needs more options (at least it does on my 5900's)

e.g.

> terminal logging level 7

2:

If you want to debug route changes, you need

> debugging route-<something-relevant> [process/nib]

not

> debugging ip address event

Here is how that looks on a 5900.

HP5900>terminal monitor

HP5900>terminal logging level 7

HP5900>debugging route-static nib

now, if - from another session, ssh or console - I do (don't cut yourself off here :)) :

HP5900] ip route-static 1.1.1.1 32 10.1.1.1

the first session responds:

HP5900>*Jan 7 02:34:23:389 2011 HP5900 USR/7/DEBUG:
Add static route 1.1.1.1/32
*Jan 7 02:34:23:390 2011 HP5900 NIB/7/DEBUG: USR add NIB 0041/0/0/0/0/10.1.1.1, id 11000001 seq 7, errno 0

*Jan 7 02:34:23:440 2011 HP5900 NIB/7/DEBUG:
USR sync NIB 11000001 to RIB, msgtype ADD, bytes 104

*Jan 7 02:34:23:491 2011 HP5900 NIB/7/DEBUG:
USR modify NIB 11000001 with nexthop 10.1.1.1:

blablabla.. lots of info revealing my routing table ...

*Jan 7 02:34:23:592 2011 HP5900 NIB/7/DEBUG:
USR re-rely route under NIB 11000001

and when i remove it again ( HP5900] undo ip ip route-static 1.1.1.1 32)

the session debugging responds:

*Jan 7 02:36:48:251 2011 HP5900 NIB/7/DEBUG: USR delete NIB 11000001 with seq 7

*Jan 7 02:36:48:301 2011 HP5900 NIB/7/DEBUG:
USR sync NIB 11000001 to RIB, msgtype DEL, bytes 36

So - it should work.

Thank U man for your input.

U right, "terminal logging" I was written by memory :)

But I found "debugging rib unr" was doing stuff I needed. I'll verify your solution tomorrow.

Thank again for your input!

Hello man!

these debug directives:

<HP>debugging route-?
  route-direct
  route-policy
  route-static

only show events regarding directly connected or static routes as well as routes manipulated by route-policies.

U will not see any insertion/deletion route into/from routing table if this route is dinamically learned route and none manipulation by route-policy is done on it.

So really correct directive if someone want to observe events with regard to routing table is "debug rib <whatever-stuff-U-need>

Anyway thank U
