Cisco Switching/Routing :: WS-C3560-24PS / WS-C3560-48PS - Port With WAP Goes To Err-disable?
Oct 11, 2012We have a Cisco switch in each office and every now and then the port that has the D-Link Wireless AP (DAP-1522) connected to it goes to err-disable state. Actually sometimes even a regular port that has a cisco phone connected may also go to err-disable state (less often). So I have to telnet into the switch and issue shut and no shut command on that interface to get it back to life, then it works for a few days or weeks until it happens again. Any suitable configuraiton for that interface, that would prevent that from happening or a workaround ?
Here's the info:
Model: cisco WS-C3560-24PS and cisco WS-C3560-48PS
Image:c3560-ipbase-mz.122-35.SE5.bin
This is the log from one switch:
31w5d: %PM-4-ERR_DISABLE: psecure-violation error detected on Fa0/2, putting Fa0/2 in err-disable state
31w5d: %PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address 74e2.f592.f7f2 on port FastEthernet0/2.
31w5d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changed state to down
And from another, which is almost the same:

5d10h: %PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address d8a2.5e31.2cf6 on port FastEthernet0/3.

Cisco Switching/Routing :: WS-C3560-24PS - Rate Limit And QoS
Mar 4, 2012I am having an issue with VoiP phones giving me an insufficient bandwidth message. I have three remote locations connected to our main building using 2 Mb point to point ethernet solutions through TWC. Each remote location has a Cisco WS-C3560-24PS running IOS C3560-IPBASE-M, version 12.2(25) and have the cable modems plugged into port 1 on them. The remote buildings are labeled 192.168.101.xxx, 192.168.102.xxx, and 192.168.103.xxx. There are 14-16 VoiP phones in each remote building. The main building being in the subnet of 192.168.100.xxx. I have the 3560s connecting to a single port on a 2801 in the main building, all using the subnet of 192.168.253.xxx The phone server sits in our network at 192.168.100.203. I have created the ACLs, class maps, and policy maps on all of the equipment.
For the remote buildings I have the following:
ACL
===========
Extended IP access list VOIP
permit tcp any host 192.168.100.203 dscp ef
permit tcp any host 192.168.100.203 eq 5566
[Code]....
I have put a hub in to capture traffic via Wireshark to see if DSCP flags are being appropriately marked and I do see that all VoiP packets are getting marked with as EF. However, I have been receiving phone calls from people in the remote buildings stating that their phones will cut out, flash Insufficient Bandwidth on the LCD displays and then the call will cut back in. I am wondering if the 2801 is not applying QoS with the rate-limits in mind since it is set to 100 Mb, or is it an issue with trying to take 3 remote locations and bring them down into 1 port on the 2801?

Apr 23, 2012I have a WS-C3560G-24PS service as a distribution switch with six (6) WS-C2950T-24 connected to it. In looking at the utilization on the inter connect links no one is running close to a gig speed and this includes the link between this switch and the core. The CPU load (6%) and memory utilization (30%) on the switch do not seem bad so what else does one watch to see if it needs an upgrade?
We are starting tohave discussions about any needed upgrades on the network. I have an ocassional user that complaines about low performance but looking through the network I can find nothing glaring on a consistent basis that says an upgrade is warranted. I am however looking at things such as the above. Utilization on links, CPU, memory, etc.
Cisco Wireless :: WS-C3560-24PS - Plug N Play Installation Method For HREAP
Aug 8, 2012I'm configuring AP in Hreap mode. Objective for me is th have a "plug & play" installation method for HREAP. I configure on HREAP AP, Native VLAN set to 1 and the WLAN and Vlan mapping for the current wlan is set to 1 too. WLC version is 7.0.230.0 and AP version is 12.4(23c)JA4
on my cisco switch (WS-C3560-24PS with 12.2(55)SE1), the port configuration is as below:
switchport trunk encapsulation dot1q
switchport trunk native vlan 45
switchport trunk allowed vlan 45,74
switchport mode trunk
no logging event link-status
no logging event power-inline-status
no snmp trap link-status
spanning-tree portfast trunk
spanning-tree bpduguard enable
AP receives a DHCP IP in Vlan 45 and users connected in vlan 45 too. I would like to undestand why the AP is working properly because normally vlan 1 is not configured as allowed vlan on my switch and the native vlan is dedicated only to untagged ethernet packet.

Oct 13, 2012Recently I changed our default gateway from a pair of PIX515 to ASA5510. Since I changed the gateway anyone connecting to our wireless VLAN/network who tries to access the Internet may or may not get a page load. If the page loads it is extremely slow and sometimes the browser page indicator will just spin like it is loading. It's not our access points, if attach an ethernet cable to my laptop and put my switchport in the wireless VLAN I experience the same problem. DNS resolves OK, ping responses are consistent with no drops and access to any internal resources are good. All other LAN VLANs/networks work just fine, it's just Internet access on the wireless VLAN. I see the correct traffic flow in the ASA packet capture. Anything in the ASA Packet inspection related to wireless networking that could be blocked? Is there a way to check for a routing loop possibly?

Cisco Switching/Routing :: WS-C2960S-24PS-L Floods Network
Jan 21, 2013I have three new 2960 switches as listed in the title. I configured them as follows:
192.168.1.215 host: whse-c
192.168.1.216 host: whse-b
192.168.1.217 host: whse-a
Switches B and C flow into A before continuing on into the server room switch (distance issues).All three switches are configured for ports 21-24 at 1000 and set as cisco switches. all other ports are undefined as they have a myriad of desktops, printers and non cisco access points flowing into them. side question - should i configure them as access points where applicable even if they are non cisco? I am replacing three netgear switches that currently are in place and have no known issues other than they are old and the fans may fail soon.hooked up .217. was able to get to it from the network. Hooked up 215 and then 216. All the sudden I lost the ability to tap into the switches, any of them. (I think I had done 215 at that point too, before adding 216. I found out later it took the network to its knees as internet was lost, and the MPLS stopped functioning.
I undid the changes and put the netgears back in service and all was right with the world again. At first I thought it was a bad host name as I had used whse-a on switch C in error. I changed that after this issue.Later that day I put 215 in place. checked it from the network and could get to it just fine. Then I put 216 in service. I lost connection to 215. I could no longer get to the internet from my pc and the MPLS went down again. This time I just unhooked 216. 215 is still in place and working on the network at the moment and not causing issues. (btw these switches are not even in my path from my pc to the internet, just on the same network) tomorrow I am going to try 217 again while 215 is still on the network and see if there are any issues adding that swtich. if I can do so, and there are no problems, is this an indication of a faulty switch? what further testing can I do, have I missed something in setup? If this brings the network down again, why cant i add two of these switches to each other/on the same network path (B and C were not even connected to each other yesterday evening when it went down again).

the intent of the above is that management connections will only be accepted via SSH, and all of those will be authenticated via RADIUS, unless it's down, then it will use the local username/pw combinations, most of which are given Privledge level 15. Telnet should never work.SSH works as expected (authenticates via RADIUS), but the problem is that Telnet also works, will ONLY use the local database (never RADIUS), and, for some reason, leaves the users at Privledge level 1, instead of the configured 15.Essentially, it seems that at every point I have told it to do something that isn't the default with regards to telnet, it ignores me.Prior to a recent IOS upgrade, the switch didn't support SSH, so the previous config was Telnet with RADIUS, and that worked fine.
Cisco Switching/Routing :: C3560 Swap Out Not Ping Across Network
Jun 17, 2012Had a switch die over the weekend, a c3560, per our normal procedure I pulled the hardware put a very basic config on it(vlans, portchannel, uplink ports, ip of management vlan, con and vty security, snmp, enable secret, and hostname). Then I use solarwinds orion to upload a copy of the old config to bring the switch back to the same state as the one that failed. Its a system that has worked for us 3 or 4 times in the past. But this time when the base config was on the box it couldnt ping across the network.I have tried clearing the arp cache and the dynamic mac tables, i verified the routing tables and even removed the 10.1.185.128/27 route and re-added it, saw the routing update go across to the other 65k, tried bouncing the edge switch(i cant bounce the 65k's), took down the po between the edge and 65k.
