On my study lab I have got 2 switches a c3560 running IOS and a c2948g-ge-tx running CatOS. Both switches has SFP ports, I would like to configure ether channel between them switches using 2 SFP ports on each switch.
My question is if such configuration is possible and how to configure ether channel so that VLANS can travel between both switches running different operating system. I have tried but it's no working,
Prime 1.3 (POC testing), for testing purposes I discovered a class C range (255.255.255.0) containing a bit of everything (AP 1240, C3560 & C3750).When looking in the config archive only the AP's have configs stored, the others failed, snmp & telnet credentials are the same for the whole range, what could I do wrong ?
View 5 Replies View RelatedWe 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:

I have two 3560 switches and i want a layr 3 ether channel configuration setup between the first 2 ports of bothe the switches. I assign IPs to the Port-channel 1 of both the switches "10.1.1.1 /24 and 10.1.1.2 /24" but i am unable to get a successful ping. what am i doing wrong. below are the configs for bothe of my switches.

I have stack of 2 switches 3750?I config etherchannel between them.
here is result
2 Po2(SD) LACP Fa1/0/15(I) Fa2/0/15(I)
Both ports are up up but standalone Int port channel 2 is down down.Need to know if this is default behaviour when we config etherchannel between stack switches?
I am installing a several new Cisco VM servers. The VM hosts are losing connectivity when we apply the etherchannel config in the core stack. VMware has stated that the etherchannel load balance needs to be src-dst-ip in order for the etherchannel to work.However, my current stack has 2 etherchannels configured to other switches through out the bldg in network closets. The current load balance configuration is src-mac.My question....when I make the change to src-dst-ip, will my network connectivity go down? I saw there was an older article on this that doesnt provide an answer just a work around. Here is the article. [URL].
View 1 Replies View Relatedi have made a topology in packet tracer related to etherchannel configuration.i am using 2 3560 switches and 1 2950 switch. Now what i want is to bundle up the redundant links between these 3 switches. The links fa0/1-3 between 2950_1 and 3560_1 switches have been bundled up but when i try to bundle the links fa0/4-6 of 3560_1 to fa0/4-6 of 3560_2 it wont work. i am using channel-group 1 mode desirable between the 3560 switches. secondly if i want to assign ip to port channels then it has to be of same subnet between 2 3560 switches right and it must be same between 2950_1 and 3560_1. But these 2 subnets should be different from one another.

I have some c3560 with system MTU set 1546 with interface VLAN10 whose MTU size is 1546 and there is no possibility to change it to another value. and we have some cisco 2600 where I can't set MTU bigger as 1500. I have a problem in establishing the OSPF adjacency between cisco 2600 abd 3560 , the command "ip ospf mtu-ignore" is set on both side but it doesn't work - the OSPF packets which are sent by c3560 are simply lager as 1500 bytes and are dropped by cisco2600.
the problem is that sometimes c7200 losses their BGP session, I would say in most cases it happens between NPE400 and NPE-G1/G2 whit error message like "session closed by a peer x.x.x.x" after some seconds BGP session goes again UP , and then after some minutes again DOWN .
it can be MTU problem, as the traffic passes those c35660 with MTU1500. The neighbour status showes that "transport tcp path-mtu-discovery" is enabled an all neighbours but it seems doesn't work. if I disable the path-mtu-discovery on the neighbours - the BGP session between them stays stable.

recently i do some lab about trunking protocol using Layer 3 switch C3560 and layer 2 switch C2960, but i face a problem that i cannot configure trunk port on my C3560 using "switchport mode trunk" command, and after looking for the answer from google i found that i have to "remove" the "auto" mode of C3560 using "switchport mode dynamic desirable" and after that we can enter the "switcport mode trunk" command successfully.
and my question are, whether the "auto" trunk mode in switch layer 3 is a default mode or not? and why i should enter "sw mode dynamic desirable" command before "sw mo trunk" command ?
I am in a doubt if the 3560-12-PC-S supports OSPF. Datasheet says we need IP Services image. But 3560-12PC doesn’t have the option with IP Services. Then I havigate to [URL] how?
So, any clues whether or not this box can run OSPF?

I am upgrading the network equipment at my place of employment. We use Cisco C3560, 2960, 4506 and I was noticing that IOS 15.0.x is available. After doing some reading it appears that Cisco is going to a pay for the licensing functionality that you want. Do I need to purchase licenses to upgrade from IOS 12.X to 15.0.x to maintain functionality?

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.
Had 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.
View 2 Replies View RelatedI have a network running some 20 switches, two controllers and many AP's. All the devices that should be able to connect to cisco network assistant can successfully. However there is one switch that will show in neighbours but will give the message of “unable to connect to device” when I try and add it to the topology.
As far as I can see the config is identically to all other similar switches in the network. I can telnet from a switch (management VLAN) to the switch in question. However when I try to ping or telnet from the PC running network assistant (different subnet) I am unsuccessful. However I can ping/telnet to all other cisco device from this PC. The switch is a WS-C3560-48TS and I have included the config for firstly the switch in question and another switch of the same model and config that works correctly.

I have a c3560 switch that has two gig fiber modules in it. I need to uplink fiber to one of these at 100mb. This is because this port will be rate limited to 20mb and 10 percent is the lowest you can go with the rate limiting command. Is there a 100mb fiber module i can insert in the 3560
View 1 Replies View RelatedWe are seeing output drops on a C3560 switchport, this port does not have QoS enabled -- application does not need special qos treatment, as long as packets are not droppd, so I suppose all traffic will share the same queue? then how should I read the output of "show platform port-asic stats drop" which indicates that it is queue 3 weight 2 drop?

I 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

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?
I have a strange problem with one switch in my LMS 3.2.1 installation.It is a WS-C3560-48TS with IOS 12.2(50)SE3 running. I have nine switches with the same type and IOS running without problems.
I notice the problem because there were no UT data for that switch. In RME and CS it was managed.Checking SNMP and config of the switch, but can't find any issues.Because at this time LMS ran in version 3.2 I installed at first CM 5.2.1 and after that the patches for CSCtd49439 and CSCtg20882.Next step was RME 4.3.1 with a lot of patches for different issues. Then I installed the patch for the internal error of CS (CSCtd07131).And finally I installed LMS 3.2.1 and patch for CSCto46927.Last step was installing the latest device packages. I did this directly from the application because it is much better handling than do a manual download. No the system seems to be fully updated.
I had the hope that CM will now find and manage this one switch. But it is still not available.I can't find the device in the data collection. But I can find it in the "Include Devices From DCR", although I configured to fetch all devices from DCR automatically to CM. To manually include the device is not working, too.
P.S. I used that step-by-step update path because it worked on two other servers very well for me.
