You can browse the entire Airespace MIB that the controllers support at: http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?objectInput=airespac e&translate=Translate&submitValue=SUBMIT with Cisco's SNMP Object Navigator tool.
As far as I know there is no single OID for the number of access points registered to the controller. It's just a table that's not indexed at all. I have a Perl script that walks the table and counts the number of rows to get the number of access points. -- Brandon Case, CCNA Network Engineer, ITaP Purdue University [EMAIL PROTECTED] Office: (765)49-67096 Mobile: (765)479-7597 Fax: (765)49-46620 -----Original Message----- From: Jim Glassford [mailto:[EMAIL PROTECTED] Sent: Friday, February 15, 2008 11:13 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Cisco Wisms CPU Greetings, Does anyone have an OID for the number of Access Points attached off 4400 controllers?
