syslog level 6 on 65xx for sys and spantree

[patrick.guerin]

Hi

Cisco's Best practices doc for 4xxx, 5xxx and 6xxx series switches states to up the logging level of both sys and spantree to 6.

http://cisco.com/en/US/products/hw/switches/ps663/products_tech_note09186a0080094713.shtml#sl

I am finding it hard to find what extra information you get with these non default logging levels.

I am particularly interested in sys

Cisco - "Cisco generally recommends bringing the spantree and system syslog facilities up to level 6, as these are key stability features to track. "

If anyone knows what extra features you get that could provide extra stability be that by proactive notification please let me know. Or for that matter what you could miss by leaving at default of 5.

Thanks

Hi PG,

Logging level 6 is for informational messages and there are lot of messages which are logged at level 6 for spantree and system messages.

Like a port state in the VLAN changed to blocking which is diaplyes as a spanning tree 6 level message.

Have a look at this link for spantree level 6 messages

http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sw_7_3/msg_gd/emsg.htm#wp1016279

A message for sys level 6 can be for ip phone like a message indicating that an IP phone is reporting a problem with the inline power it is receiving on a port.

Have a look at this link for all sys level 6 messages

http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sw_7_3/msg_gd/emsg.htm#wp1016897

I think this will give a fare idea what all messages at level 6 for STP and SYS will let you fast analysing and can result in fast recovery of possible arising problems.

HTH, if yes please rate the post.
