Cisco :: Catalyst 3560s / 3750s - EEM And TCL Script To Disable Inactive Ports
May 4, 2013
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 several 2960s and 3750s and two 6506 (ws-cac-3000w) recently move to new location The power outlet is the same ,but Volt is different current 2960/3750 use this(one phase 3 wire) 220v and new location change to (from 3 phase 4 wire -> one phase 220v)6506 current using(one phase 3 wire) and will be change to (from 3 phase 4 wire -> one phase 220v)
I had search doc about power supply /cable , only show support single phase 220 v ,but not description vlot between each wire !!Does new location power outlet suit for 2960/3750s power and 6500 ws-cac-3000w ?!? Do I need chane power outlet back to current using?

I have the BEFSR81 V2 and every day at least one of the ports become inactive and the router has to be unplugged and plugged back in to reset the ports. I was going to upgrade the firmware from version 2.44.2 to the one on the site 2.45.10 but when it is downloading I get a message at the end upgrade file pattern error. There is a problem with the router that the ports go out or will the firmware update hopefully correct that issue and how to I get the firmware to update

I am replacing some WAN connections: Point to Point T1's (running from 2820's to a 7200). I am replacing them with metro Ethernet connections with a 3560 layer 3 switch at each end. We run Cisco Call Manager, and have IP phones at our locations. I want to set up QOS on my WAN connection to make sure my packets arrive in the correct order. I have a few remote users complaining of voice problems, crackling, etc. The 3560's are acting as routers, and don't directly connect to all the phones. So I won't be using the mls/auto QOS features, I don't think. I am trying to use service-policies and class-maps to handle qos, as I have done in the past, but I'm not finding the correct commands. This is the QOS I currently have set up on my 7200/2820

I have a customer looking to deploy OEAP & wants to know if it possible to disable the local ports 1-3? Reason being, they don't want the home user connecting devices & causing more support tickets to troubleshoot an Xbox or Google TV just b/c it's connected to a company provide AP/Switch. I have read all the docs & it makes no mention of this.... I can see in 7.2 the ability to disable the local SSID but no mention of the ability to shutdown ports 1-3..Also see support in 7.2 for Dual RLAN... but that still leaves 2 local ports.

im working in company that develop high speed networking equimpnet(Mellanox)we develop 4056GB network cards and switches.we have developer network on HP pro curve switchs, the engineering make tets on servers with the high speed network cards and sometimes the test "go out" from the 4056GB network cards and switches and "boombing" the regular network of 1G in hp swiches.i meen every server are connecting with RJ-45 cable for access to the server and the real work is on th Mellanox switches and network cards but sometimes the test "run away" to the ethernet network and 40G traffic are killing the network.function in HP switches that recognize over booking traffic and automatic disable the bombed port?now we have spening tree and brodcaste limit on every switch but its not enough, the big traffic kill the network until we disable the problematic port and igonre the bombing server.we have hp procurve 5610 layer3 switch and pro curve 2510 switches.

In my ongoing project i need to monitor cisco 3750-X port status (uplink/downlink) i.e. whenever there is some problem at a specific port. I need to monitor it through an OPC server and right now what i am doing is as follows: i am using Kepserver and i have added SNMP driver in it for that purpose i am not a networking expert but what i have learnt till now is that SNMP agent (that resides in switch) delivers the status of MIBs to SNMP manager ( which in my case is kepserver (opc server)) for the above purpose i am adding IF-MIB to monitor OID 1.3.6.1.2.1.2.2.1.8 (which shows port statuses) but when i add that in OPC server then it indicated that this OID is not available in the Switch ( it might be disabled) so i need to ask if there is any way to enable OID's in a switch,

I have an E2500 and i need to disable the ports on the router. I have a DSL line going in and thats it. I do not want it to be able to accept any wired device and have someone get on the internet. I do not want someone to just take a laptop, with a LAN able, plug it into a port, and get internet. How would i be able to disable the ports?

I have a Catalyst 2950G when I activate the switchport port-security, but I want to empty the black list of mac address because every time I connect a device, the port is automatically désacative, here is the port configuration:
!
interface FastEthernet0 / 2
switchport access vlan 17
switchport mode access
switchport voice vlan 51
[code]....
I tried the following commands to clear the blacklist mac address of that port, but the problem is still relevant:
# Clear mac-address-table dynamic int fa0 / 2
# clear port-security all int fastethernet 0/2
# clear errdisable interface fa0 / 2 vlan

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.

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 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 just inherited a network which has 7 switches (3750s) as a Stack. In there, there are 5 SVI (switch virtual interfaces) and in each of these VLANs, HSRP is configured.
Question:Is HSRP really needed in a Stack configuration?If so, what are the benefits?Can I simply clean-up the config and remove HSRP?

Got a mind-boggling issue with a Gig0/2 port on Cat2960 48TTL, the port seens dud. I cant enable it, its not shutdown either. However, when I restart the switch, on CNA, i can see the interface flash amber (as all ports do when restarted) and goes grey. The cable is ok and works on other interfaces on the same switch. Without having to buy a whole new equipment, is there a way I can test wether the port is faulty, as in physically, or I have missed something.

i was just asking if it is possible to create a L3 etherchannel between 2 single 3750 switches that act as our core, (running HSRP for the vlan and with a port-channel between the two) and a new switch stack of 3750s that will be routed to and managed by another party. Only i'd like to have the redundancy of 2 links connecting the new stack.If it is possible are there any best practices or preference in using PAgP or LACP or just going for ON.

If we have 3 stacked 3750s# running Layer 3. Do we need license for every switch? or is it one license for the 3 switches? Also is the license associated with the MAC address of a specific switch? What i# am trying to know also, is if we have to install one license and it is associated# with one MAC and this switch failed.. will the Layer 3 be broken?

Two people went on a business trip with their laptop and when they came back they could no longer access the data server. Cannot map the network drive either.
1. Every desktop PC in office can see and access the data server fine.
2. We have a DHCP and DNS server (on one PC; Windows Server 2008), but we had to shut down the services because internet and email didn't work when the DHCP and DNS server service was on. I am confident that this is due to the recent shutdown of the company e-mail server (now outsourced) and the server settings needs to be reconfigured. The described symptom persists even when the DNS server service is stopped.
3. Upon taking a closer look at the DHCP reservation settings. The reservation status indicates as "Reservation (inactive)". I don't know the MAC address of the device, so I have no idea if the values are correct. Tried rebooting the server, delete and recreate the reservation, reboot router; no cigar.
4. Using the coworker's laptop, the data server is shown in the "Other devices" section even with the DHCP sever disabled, but shows error that it cannot access it.
5. All users, with the exception of the data server, have dynamic IPs assigned.
6. DHCP, DNS server is set to 10.10.10.2, Router is set to 10.10.1, Data server is set to 10.10.10.175. 10.10.10.2 is also an accounting server which can be accessed by everyone even in the midst of this mess.

My company has a DCS network that was previously segregated with a layer 3 switch and a handful of access lists. However, there came this big push to segregate all DCS networks with Firewalls, so I purchased a 5505 and duplicated my simple access lists on the firewall and everything worked. There is no NAT, just explicitly permitted traffic out and explicitly permitted traffic in. However, there are some applications that connect and work fine for a few hours, then disconnect and the user must exit out of the application and go back into it, then it starts working again. Previously with the Layer 3 Switch/access lists, this never happened. Since I put the firewall in place, it has happened 3 to 4 times a day every day for the last week.
