Cisco Wireless :: Two 1252 On Ports 1 And 2 On Catalyst 3550 Resets
Oct 12, 2012
I have two 1252s on ports 1 and 2 off a Catalyst 3550. No other device on the switch except the fiber uplink.
Initially 1252 #2 (on port 2) resets for no reason at no specific time. We did not have a problem with 1252 #1.
The show ver on #2 does indicate that equipment resets due to power. I figured the 3550 is having problems powering two 1252s so had this AP on PWRINJ4 (validated its not drawing power via show power inline).
Today, #2 does not reset. However, now #1, which is the only device using inline power is now resetting. Same thing, reset due to power. Same weird behavior, at no particular time.
I've also have "no cdp enable" out off each port as i understand CDP sometime cause device to not boot up (15w versus 15.4w issue).
Both AP btw are Standalone IOS.

we are using the catalyst 3550 L3 for BGP routing. For e.g. Gi 0/4 is our internal interface tha we want "switch".
We need on Gi 0/5 the same network that is on gi 0/4.
How is it possible? Make it like a 2 port mini switch. Or make a bridge of these 2 interfaces without any complicated reconfiguration needed?

confirm whether the Catalyst 3550 with IOS Rel. 12.2(44)SE is compliant with POE IEEE 802.3af? I see some conflicting informaiton on Cisco's web site. Before Release 12.1(22)EA2, Catalyst 3550 PoE-capable switches (without intelligent power management support) caused high-power powered devices that supported intelligent power management to operate in low-power mode. Devices in low-power mode are not fully functional.
IEEE 802.3af—The major features of this standard are powered-device discovery, power administration, disconnect detection, and optional powered-device power classification. For more information, see the standard.

I have 2 3550's connected across a wireless link. [code] However, from Switch A, I cannot reach 10.1.3.9Can this 3550 not route traffic between 2 routed ports?

I live in a condo building that uses 3 Cisco Catalyst 3550 switches connected to a Comcast router with 100 Mbps download. Currently we regulate bandwidth by providing each user with 3 Mbps download. Even if only two people are active they still only get 3 Mbps download. I would like to set it up so if two people are using they each get 50 Mbps; a sort of 'dynamic qos. Is this possible with these switches? Would we have to purchase a Cisco router in order to provide this feature?

I can assign IP addresses to any of the 24 FastEthernet ports (it is a 24 port switch!). However, I have fitted the WS-G5482 Gigabit adaptor to give me Gig ethernet capability. It does not seem to be possible to assign an IP address to the adaptor.I realise that as it is an 'add on module' (well, a plug in module) this is different to the 24 port in the 'body' of the switch. I also have read that these Gig adaptors will only connect to other Gig adaptors (I found that out by trial and error, and then confirmed it by searching here).it's not possible to assign an IP addy to one of the plug in modules; it is not a big deal but I am planning to assign some IP addresses for remote management etc. I was going to use the Gig port for this but it may not be possible.
AH PS I am using the switch and connecting to the internet via the Gig adaptor, then out from one of the fastethernet ports to another little switch and then on to a router and out to the internet, so the switch and the plug in module are working fine.

I am attempting to create a mass upgrade server for some of our more standardized equipment since our vender cannot upgrade them pre-shipping for us, we've got to do them on our own. This means using a terribly organized wizard written in what appears to be Java...
I have an aversion to Windows and felt that I could accomplish the same thing using expect scripts and a Gentoo Linux server; now all I need is to set my Cisco 3550 (c3550-ipservicesk9-mz.122-44.SE6.bin) to have each port on it's own VLAN, except for fa0/1 which will be a trunk port to communicate with all ports as well as the server.

correlates the older IOS format naming compared with the newer? I have an older catalyst 3550 that might need an IOS upgrade due to us starting to implement dot1x. The reason that I say this is that some of the commands in the dot1x config guide, such as aaa accounting dot1x, are not valid on this platform. The current IOS is c3550-i5q3l2-mz.121-8.EA1c but the newer format is the ipbase, ipservices, etc. format. There is a newer ios but how do I convert from one to the other? I think I need to research the IOS to see if the new commands are there as well as I want to make sure there are no gotchas from a hardware standpoint if I upgrade.

I have a catalyst 3550 and will be using it to run my cisco 7940 and 7960 ip phones with POE. When I plug the phones into the switch they power up just fine but the phones will not dial out as they have little x's by the line. I have also tried going through the set up of the 3550 but get stuck in one place. When I go to the 10.0.0.0, the screen will not allow me to enter the telnet page or allow me to enter any information. In the manual it shows a pic of what the screen should look like when I go to 10.0.0.1, but I am getting an entirely different page.
What I need to do to get everything set up correctly?

I am replacing an old Catalyst 3550 (that has 2 Gig ports) with a 3750 (that has 4)- I used the exact same configuration in the new switch. When I plugged in the new 3750, the trunk ports started blinking from green to amber. I dont know why this is occuring- it SEEMS to be fine, but we havent thrown a whole bunch of traffic over it.

I have a test switch (Cisco 3550) that I want to set up with 6 Vlans and 2 trunk ports. I want to be able to access a virtual server conected to the trunk ports from the switch ports. Ports Fa0/1 to 8 are in a vlan port fa0/9 to 16 another vlan etc. Ports Fa0/47 and 48 are the trunk ports. This is a lab environment so the the switch is the only device being used.

Is there a way to configure a switch (3550, 3560,3750) to disable a switch port if it has not been used for a specified time period such as weeks or months. Say you want the switch to disable switch ports that have been "abandoned".

I am testing on lab equipment (2 Catalyst 3550 and 1 Catalyst 3560) HSRP version 1 and 2.I successfully created a load balancing between the two Catalyst 3550 on a couple of vlans (11 and 12) on ver 1
now, just adding the command "standby xx version 2" my hosts on the 2 vlans are completely unable to ping the virtual IP def. gw on debugging i checked that msgs are exchangedthe two cat 3550 are seeing each other on HSRP (active / standby roles)the real ip addresses are pingable rebooted the swiches (just as a last resort try)deleted arp chache on hostsremoved the auth on hsrp all of this no effect.
i also tried to modify the priority on the cat 3560 (before he was on both vlans in standby) to make it the active one and with the same config it worked flawlessly.
My only idea is that there is a bug on CATs 3550 (IOS: c3550-ipservicesk9-mz.122-55.SE4.bin) [code]

I am configuring TACACS Authentication on Cisco 3550 switch .It has Version 12.2(25)SEA IOS image. A strange thing is happening, whenver I am enabling AAA new-model on this switch, and then after enabling I see ruuning-config . It shows me this
tacacs-server host x.x.x.x
tacacs-server host x.x.x.x
no tacacs-server directed-request
tacacs-server key 7 xxxxxx
radius-server source-ports 1645-1646
* included here to hide the specific information I dint specified any RADIUS server , why it is showing me radius-server source-ports 1645-1646 after enabling AAA New-Model As soon as i give "no aaa new-model", this parameter also vanishes. I think this is the only reason I am not able to do tacacs authentication.

Are all ports on Catalyst 4500X Gigabit/10-Gigabit or just the ports on 8-port module. We are looking at 4500X for campus distribution layer but need Gig ports to access switches for now and may year from now will be using 10G.

I work at a hospital and we have 3750X-48P switches in stacks in various locations throughout the hospital. We have noticed that when an EKG machine is plugged into one of the ports on some of these switches and the EKG machines are set manually to 100/Full, the ports are no longer usable until the switch is restarted. The switch is configured for auto. If the EKG machine is set to auto, it will work and not cause problems. The link on the interface will show up/up and there will be output packets increasing. However, there will be no inputs on the link and the port is unusable. Unfortunately, even when the device is removed, the port becomes unusable for any device. Is there any way to fix this problem without rebooting the switch?

I've browsed around to the other support strings to make sure I didn't miss anything, but I can't seem to get this to work. I have the latest sl_suspend_ports.tcl and tm_suspend_ports.tcl created by Joseph Clarke from strings that verified they worked as planned. Here are the commands I issued to register the scripts -
Directory of flash:/policies/
9 -rwx 3101 May 3 2013 07:58:03 +00:00 sl_suspend_ports.tcl
10 -rwx 4669 May 3 2013 07:58:44 +00:00 tm_suspend_ports.tcl
conf t
event manager directory user policy flash:/policies
event manager policy sl_suspend_ports.tcl
event manager environment suspend_ports_days 1
[code].....
It doesn't appear to work though. Essentially, we have a need to make sure all computers are always on and all ports not active for >24 hours to be shutdown and moved to a designated vlan (I added the 'lappend' statement to the script to specify the additional command of assigning the vlan) I'm running 12.2(55)SE7 on Catalyst 3560s and 3750sIs there a way to manually run the script? Did I miss anything in the configuration?

I have a Cisco Catalyst 4507R+E (with Sup7-E) and two blades; one WS-X4748-RJ45V+E and one WS-X4648-RJ45-E.
When I connect a device to a port on the WS-X4748-RJ45V+E blade the port will not come up, show interface shows the status as "notconnect". When I connect the same device to the WS-X4648-RJ45-E blade the interface comes up.
The WS-X4748-RJ45V+E blade seems to have initialised okay, it appears in the output of "show module" as OK.
I get exactly the same effect on a second, identically configured Catalyst 4507R+E.
The software version is IOS XE 3.1.0SG, which according to the release notes supports the WS-X4748-RJ45V+E blade

I have a Cisco Catalyst 2960 series switch. When I connect another switch or a VMWare Esx server on one of the ports, the port blinks for few seconds and then goes off. When I connect a desktop or laptop or a windows server the ports stay led and I can access resources on the network. However, when connect another switch or a vmware esx server, the port is disabled.
What config in the switch can I check to make sure the ports stay on regardless when I connect a desktop / laptop, switch or vmware server?

We've got a doubt about the uplink ports of this supervisor. I've read that you have to use the four ports in 10G mode or in 1G mode, but not use for example 1 port in 10G mode and 1 port in 1G mode:
But, you can read in another sentence: " Beginning with Cisco IOS Release 12.2(25)SG, you could simultaneously deploy the dual 10-Gigabit.Ethernet ports and the four Gigabit Ethernet SFP ports on the Catalyst 4503, Catalyst 4506, and Catalyst 4507R chassis." Is it posible deploy simultaneously both type of ports?

I have a 2Wire 2701HG-B modem/router provided to me by AT&T for my DSL service. I have one issue and a seperate question sort of related to it.The issue I'm having is that whenever a laptop gets online with wireless internet the modem will randomly reset connection.Some times it will do it every 30 seconds, some times it will be once an hour or even more.It works perfectly fine on any laptop when plugged in with Ethernet cable but only with wireless it will glitch out. It does this whether it is the only computer online on the network, and also when there are a few others online so it's just the simple fact of the wireless resetting it somehow.I've done lots of google searching and some people say changing the line pair settings fixed it for them. Some say changing from b/g mode to just g mode fixed it. I've tried every thing that I've come across and nothing has worked so far. Apparently this is a very common problem for this model I just can not find the right solution that has worked for other people, to work for me as well.
if I were to want to make this modem/router just a modem and hook up my own router for N wireless would this be possible? I know I've read ways about putting combos in DMZ mode or something but I don't really know what I'm looking for because everything is worded different in this modem's settings.Can any one provide any insight as to if this is possible, and if it's even worth it to do so? Mainly worried about the first thing I mentioned though, this is just a side note.

I have a couple of 114n APs in my network and the CAPWAP uptime and AP uptime are almost the same. But there is one which always resets after some time. I have moved across to another switch port but the issue persists. I have other 1141 and 1131's on this switch and no problems. The keep alives between the AP and Controller is regular. I can't get more info from the traps as the reason code is always;
" AP associated to Controller is UP. Reason: Radio interface reset due to Init"
"AP associated to Controller is down. Reason: Radio interface reset"
"AP associated to Controller is UP. Reason: Radio interface reset"
####Only 2ice was the reason code "Operator changed 11g mode". I have seen some posts about similar problems but there hasn't been any concrete solution provided.
note that RLDP is disabled, Primary discovery timer is 120sec, and the version is 7.098

I am replacing an older AP with a new 1252 unit. I attached everything and powered it up, but my DHCP server does not appear to be finding it and assigning an IP address. The status light stays green and the ethernet light blinks randomly green. Seems to be connected fine, but without an IP I cannot configure it to use it.
