WiSM Interface Problem/Question
Though I have not completely ruled out our network... I am seeing individual VLAN interfaces (these each get IP addresses) on WiSMs that occasionally fall off - just stop responding. The net effect is that a given SSID is still present for clients to attach to, but the interface is gone, so there is no network usability. If I delete and recreate the interface, functionality is instantly restored. (or if the controller is rebooted). This is happening across three different 6500's, several different WiSMs Have ruled out duplicate IP addresses, and some ARP history is showing two MAC addresses (same root MAC, last digit varies as is seen when MACs are dynamically generated) for the same dynamic interface IP address, and in some cases the same MAC is showing up for the AP manager interface and the dynamic vlan interface. Not implying that all of this can't be explained, or that there is an issue with the WiSMs- but wondering if anyone else has seen any similar symptoms and found answers. Feel free to respond directly to me if you prefer. Regards- Lee H.

Odd PoE Message - Cisco 3750
All, I was wondering if anyone out there has seen this error. It was taken from the only two switches out of my sixty + switch network. They are all model Cisco WS-C3750-24PS-P. They are running firmware c3750-ipbase-mz.122-25.SED1.bin. All of my sixty switches are running this firmware. Only 2/115 APs are generating this error. Error (repeates itself): Sep 20 12:05:31: %ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Fa1/0/1: Power Controller reports power Imax error detected My port configs (identical for 115 problem-free APs, and 60 + switches): interface FastEthernet1/0/19 power inline consumption 9600 switchport access vlan 99 no mdix auto I am using BlueSocket APs, model BSAP-1540. Cisco's website does not have the exact full description of my error in searchable text. The general issue they say, is caused by a type-1 Token Ring device. These APs are Ethernet. I have tested the cables, tried different ports, reloaded the switch, changed the configs around, etc. The only thing I haven't done yet, is RMA the AP. Before I do so, has anyone out there come across this yet? -- ___ ___ Fishel Erps Sr. Network Infrastructure Engineer School of Visual Arts Work LL: 212-592-2416 Work Cell: 646-201-2766 Fax: 212-592-2243 E-Mail: [EMAIL PROTECTED] ___ ___ ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.

I have seen this problem a couple of times, but it has disappeared before I could finish troubleshooting it.

RE: [WIRELESS-LAN] WiSM Interface Problem/Question
I'm told that the dynamic interfaces, despite having IP addresses, aren't reliably pingable. They can drop off from ping (as I'm seeing) and to test whether it's really down, you have to ping an attached client (I'm not making this up). I'm also told that starting with 4.1.185.0, these interfaces can be considered trustworthy for ping-monitoring. Lee H.
