I am having a lab switch. Recently I am getting "%SCHED-3-SEMLOCKED: SNMP ENGINE attempted to lock a semaphore, already locked by itself" message and the switch has started to hang a little bit. I just want to know what this log means and how to trouble shoot.
I'm using C3750, version 12.2(25)SEE3
I need to add another SUP engine on Cat 4507R switch, with a new one. I have old SUP engine running in this switch. Sometime this switch is reloaded without any reason. So we want to add another sup engine for redundancy. What is the procedure to do this & also how much outage time would it cause? Which sup engine will be run as primary and which one should be redundancy?

I buy a Cisco 4003 Switch with Supervisor Engine I but it only run CatOs and i whant it to run Cisco IOS so whitch Supervisor Engine can the Cisco 4003 Switch run? i have look at the Supervisor Engine III it can run Cisco IOS and Layer 3 but can i use that in my Cisco 4003 switch?

How to configure the SNMP. any Links provides the required info with an example of configuring snmp will be really useful.
we have OPEN NMS, SPLUNK, MYSQL monitoring tools.
I have a snmp trap sent every 30 seconds from one of my cisco switches (a stack of 3750 to be precise): ccStatusMemberStatusChange. Do you know what it is and why it is sent continuously?
View 1 Replies View RelatedWe have a stack setup with 2 C3750x-12s and 5 C3750x-48p switches. We have two of these stacks. One is working and responding with snmp just fine. Our second one is showing the errors in the logThe only difference i see between the two stacks right now are the sw versions.

The job doesn´t fail but the log ICServer.log doesn´t got any information and it works for hours and hours and when it finally stops I can see that devices are not attempted.
I have done some succesfull Inventory Collections with Cisco 3750 switches and 805 routes. I have tried witch Cisco 2811 routers and 2950 and 2960 switches but it doesn´t work.
I have tried to update my LMS4.0.1 but it doesn´t find any actualization. However, in the Cisco download page there are some patches.
I am trying to setup SNMP v3 on a 4948E switch here is what I have done so far:
snmp-server location "location"
snmp-server contact IT Admins
snmp-server group SNMPgrp v3 priv read SNMP-ro write SNMP-rw access 80
snmp-server user snmp_user SNMPgrp v3 auth sha xxxxxxxxx priv aes 128 xxxxxxxx access 80
What else am I missing and how can I confirm that it is configured correctly?
I have been reading the postings on this site trying to retrieve the MAC address for the client devices (computers, printers) attached to our switches. We have approximately 500 switches and I need to map the mac address to the switch. It appears the OID information is for SNMP v2. We are restricted to using only SNMP v3. I have tried using the Cisco SNMP Object Navigator without any success.

What I would like to know is what are the effects of having the master switch itself lose power? Does it immediately just make the member take over master (there should be no election since there are only 2 switches??) and there would be no loss of connectivity?

I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net.
My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20
I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to (vlan2)my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to go out to the internet. I think it has to do with the routes. [code]
I have the task of replicating the router config on a 3825 router on a 3750 switch. Reason is we are taking out the router and replacing it with the switch to make use of the router for other functions.
Below is main part of the router config:
!
ip source-route
ip cef
!
!
multilink bundle-name authenticated
!
license udi pid CISCO3825 sn FCZxxxxxxx
!
vlan internal allocation policy ascending

The 3750 switch I have runs C3750E-UNIVERSALK9-M, Version 12.2(55)SE3 on a LAN BASE license.
The first thing I have done is to order for a license upgrade to IP BASE which would give the support for OSPF routing.I do not see much of an issue with the Interface configs, however, I am not too sure about replicating the routing config on the switch.
My question is can I run the commands as shown for the OSPF routing on the switch? If not, can I get suggestions on how best to set this up on the switch?

View 3 Replies View RelatedI'm running into what seems a basic ip routing config problem with a Catalyst 3750 (IP Base) switch. I have several VLANS configured on the switch with IP routing enabled, and the switch is connected to the inside interace of a new ASA 5520 as follows:
ASA5520 IP (Default gateway): 192.168.1.1Switchport Gi1/0/1 is configured as a routed port, IP address 192.168.1.3 255.255.255.0Example VLAN is VLAN 100, IP address 192.168.100.1 255.255.252.0 From the switch CLI, I can ping all VLAN addresses, as well as the ASA5520, and the client laptop I'm testing with from VLAN 100.
From the client laptop on VLAN 100, I can ping all switch interface and VLAN addresses (inter-VLAN routing is working), including 192.168.1.3, but I CANNOT ping the default gateway at 192.168.1.1.
Here is the relevant configuration information on the 3750:

View 2 Replies View RelatedI had a bad expirience with Switch 3750-X. Because of an auditing security processess, my customer ran a software called "Nessus" to do a scanning of vulnerability on the network. When this software is point to switch, the process of the switch will next to 100% and reset. The software only do a listening on the ports to see what ports are opened and the switch should not reset because this. Bellow is the log os switch on the moment of test; we note that the processess 'HTTP' rise moments before the switch reset. I disable the HTTP service on switch but the problem persist. The test was made only one machine connected to switch.

View 3 Replies View RelatedThe question is: Will a 3750 switch route Jumbo frame sizes (e.g. 9000 MTU)?
We know that we can change the System MTU to 9000, and someone on a previous thread said that we can change the Routing MTU to 9000 as well, although I couldn't figure out how to do that. However, regardless of how we configure the System MTU and Routing MTU, I don't think we're able to adjust the MTU on L3 VLAN interfaces, so if we want to actually "route" between VLANs on the switch, we're limited to 1500 MTU.
Our situation is that we have a customer connecting to our 3750 switch, and this customer wants to use Jumbo frames. The customer connects to our 3750 switch via their own VLAN, with their own L3 VLAN interface configured on the switch. The customer will point their traffic towards the L3 VLAN interface, then we want to route them onto another VLAN, via a different L3 VLAN interface, before forwarding their traffic. Because of the limitations noted above, specificially regarding the routing between these VLANs via L3 interfaces, I do not think we'll be able to support 9000 MTU frames on this 3750 switch. I think the L3 VLAN interfaces will limit us to 1500 MTU, regardless of what we configured via the global System MTU and Routing MTU settings.
How do you properly remove the QOS queues and configs from the switch.A was using auto qos which created a whole mess of qos configs on my running-config. I did "no mls qos" in conf term but that did not remove the queues.

I connected a console cable and power cycled the stack. I see the flash initialize and then the IOS image start to load. Lots of @ symbols and then nothing. It just sits there. The system light on the switches, while flashing green during the load, is now off. No light at all. But fans are running and the process will repeat itself if power cycled.
i have standalone 3750 switch. RPS light is green and system light is off.
