I would like to test the possibility to reload devices via SNMP for new switches like 2960, 3560 and so on.I know that the command "snmp-server system-shutdown" has to be configured, then I need to send the set query to the device via SNMP.
I have found on the net the OID 1.3.6.1.4.1.9.2.9.9.0 but it belongs to an old MIB and doesn't seem to work with new switch models.
I have the following problem with
Situation:
- 2x 3750G-12S Distribution-Switches (DS) and several 3560/2960 Access-Switches (AS)
- redundant Fiber optic uplinks between AS and DS
- Cross-Stack Etherchannel config on all uplinks
- UDLD aggressive mode configured on all uplinks
Problem:
- when I reload the DS and the switch comes up again, I've lost the connection with several (not all) AS
- looking at the AS log I found the following error message: "%UDLD-4-UDLD_PORT_DISABLED: UDLD disabled interface Gi0/1, aggressive mode failure detected"
Cause:
- in the log of the AS I don't see intf Gi0/1 go down during the reload of the DS
- this means the DS didn't shuts down all its ports during the reload
- but this also means that UDLD on AS didn't know about DS reload, and therefore didn't resets counters
Workaroud/Solution
- I'm now configuring errdisable recovery on all AS
So I'm forced to configure errdisable recovery, even if I don't want.
I uploaded a new config file via TFTP to a 3560 switch. What are the order of commands to get it to boot from this new config file instead of the file listed in 'sh boot': [code]

How I will configure the 3560G to make communicate with 2960G and bring all these 9 ethernet connections to server. All the 9 connections are from different IP. and server also have different IP.
It seems my 2960s and 3560s switches have enough flash space and memory to support the 15.0 IOS should I be OK to jump to this from 12.2(35)?

View 11 Replies View RelatedI want to implement port-based and MAC-based in these two switches: 2960 & 3560 (both of them have this IOS version: 12.2(55)SE1). And I haven't found a way to implement both of them at the same time. This is what I got:
ip dhcp use subscriber-id client-id
ip dhcp subscriber-id interface-name
ip dhcp excluded-address 192.168.0.0 192.168.0.2
ip dhcp excluded-address 192.168.0.251 192.168.0.255
[code]....
With this configuration I can use port-based, but not MAC based. If I remove the first two lines and change the last line for this one:
address 192.168.0.7 client-id 0112.ae1d.af58.60
Then, the computer with that MAC address got the correct IP, but then the port-based doesn't work. Also, I got this line in the interface what I want to use MAC-based:
ip dhcp server use subscriber-id client-id
Is it possible to daisy chain from a 3560 to 2960-S switch using a SFP interconnect cable (daisy chain cable)
View 1 Replies View RelatedWe have quite a few 3560 & 2960 on our edge network - what I have been looking at was to access switches via web-interface i.e. web-browser. Only problem with this is it always gives you access on privilige level 15 which is not ideal as not all who we decide to give access to these switches will be admin and allowed to configure these swicthes - In the 3560/2960 data-sheet states:
"Alternatively, a local username and password database can be configured on the switch itself. Fifteen levels of authorization on the switch console and two levels on the Web-based management interface provide the ability to give different levels of configuration capabilities to different administrators"
Where as there is no mention of how to configure these two levels of Web-based management in the configuration guide.
As per the attached diagram: How do I configure the 2 ports on the 3560 (Ports 6 & 7) and the connected ports on each of the 2960 switches (Port 25) to provide redundancy.
If the up link from Switch A dies then I need the traffic to flow through the trunk and utilize the up link on Switch B with minimal delay (milliseconds).
I have a Cisco 3560 running as a Level3 device in my network running 10 V LANs and routing between most of them (nothing complex with ACLs) and running spanning-tree mode pvst. The main network is run on a net gear GS748TPS stack of three switches running MSTP.
I have just bought an additional 3560 and a 2960 to plug in. I have set them up with IP addresses and then plugged them into the net gear. This brought the whole network down until I unplugged the new switches.
I have confirmed the IP addresses aren't duplicated and that DHCP is not running on the switches so I can only assume it's something to do with DHCP. I cannot afford for the network to go offline again, so is there anything I should check? Am I running incompatible spanning tree methods between the net gear and Cisco devices?
I am using Packet Tracer to simulate Cisco networking.As the existing IOS of the 3560 and 2960 switch are in older version which has no new feature in new IOS, how to upgarde the IOS of Cisco switch at Packet Tracer?
View 5 Replies View RelatedI've just purchased a new Cisco 881.I'm using NAT NVI for my inbound static mappings. However, regardless of the fact that the config is saved to nvram, after a reload of the router, the NAT mappings are setup as traditional inside/outside mappings. This means that inbound connections in to the router on the required services fail, until someone logs on to the router and re-applies the NVI mappings.

SSH has been enabled on our one and only 4507 switch for several months and working fine. A few weeks ago the switch had to be reloaded and when it was back online I couldn't SSH to it. When I connected via the console and typed "show ip ssh" it came back saying I needed to generate the keys. Did that and it starting working again. The same switch had to turned off and on the other day due to a power down in the server room and when it came back the same thing happened again!!
The version of IOS is: cat4000-i5k91s-mz.122.20.EW
I have a cable from an SFP module in a WS-C3750-48P with 12.2(55)SE1 running to a Gigabit port on a Cisco WLC. After the switch recovers from a power failure, the gigabit autonegotiation fails. The cure is a long drive to unplug and reseat the SFP. Note this happens at too many similar sites for this to be a loose connection. Interface shutdown then 'no shutdown' is not sufficient. The state is 'line protocol is down (not connected)'. Interface is configured for switchport mode trunk (auto speed, auto duplex). Command 'switchport nonegotiate' makes no difference. Is there a more powerful command than 'shutdown' which might toggle the interface signals? Is there some way of resetting the SFP? sh int gi 1/0/1 displays 'media type is 10/100/1000BaseTX SFP' and zero packets received.
View 4 Replies View RelatedLast night, the C6509-E do a unexpected reload. In the crashinfo, I can see that the last error message before the reload, was as follows: %C6K_ PLATFORM-SP-2-PEER_RESET: SP is being reset by the RP
I consulted the cisco website about this error message and what I found was the following:C6K_PLATFORM-2.
We have a backup sup 720 which has a 2 gigabit ethernet though port channel, to another chassis. Suddenly UDLD detected an error and got into err disable, then this err disable didn't let the interface set to DOWN, and created a switch loop, then our Supervisor reloaded. I'd like to know what could have caused this reload. In my opinion could have a been the switch loop, but also I've been checking from the output interpreter the show tech and might have been a bug, the only one that could match in IOS version 12.2(33)SXH, is this one: url...
We're going to disable err-disable next time I guess and recover the link manually, apart from that what could have made the sup for crash and reload?
Suffered a big outage on the network, the fix was to reload the module 3 on the 6509 switch, we had these errors on the log %CONST_DIAG-SW1_SP-3-HM_PORT_TEST_FAIL: Switch 1 Module 3 TestUnusedPortLoopback Port(s)[24,46] failed. System operation continues.in the end, we reloaded the card and it was all ok. is there anything I can do to check the card / or any deeper logs? would that error cause the card to crash?

I have a problem with the Cisco 881 router at one of our customers.It seems that after a "no shutdown" has been given on the Vlan interface, it still goes back to "administratevly down" after a reboot.So when I restart the router I always have to manually "no shutdown" the Vlan interface to come back up.While rebooting the router it also gives the following info in the console screen every time which is strange:
new interface Vlan1 placed in "shutdown" state.We tried several different firmware releases.
Replacing the router with a new Cisco 881 router did not work either. After they sent back the old Cisco 881 router we tested it here and there were no problems, we weren't able to replicate the problem.The configuration we use for the router is correct, we use it for hundreds of customers, so that can't be it either.The customer uses a fortinet firewall behind the router. Could it be that something inside the LAN of the customer that triggers the Vlan to shut down?

My hunch is its software but i cant find any related bugs. It could be hardware issue as well ?
