Right now i am able to access the router . whats this error about -- is router going to crash or reboot?
Can a C3560-24PS switch with 32 MB flash be loaded with IOS 15? Will it be able to execute the code and function properly?
View 2 Replies View RelatedI am not on site and I have not seen a WS-C3750V2-24PS-S. Customer has a stack of 6 x WS-C3750V2-24PS-S and one unit has failed. We do not have a WS-C3750V2-24PS-S spare. Can we replace it with a standard WS-C3750-24PS-S (not V2) switch and be part ofthe stack.
1. Are there any traps gotchas?
2. What about IOS versions - aren't they different for V2 switches
3. Are the stack ports and stack cables same for both WS-C3750V2-24PS-S and WS-C3750-24PS-S
4. What is the main reason for bringing out the V2 switches. What features do they have extra?
is possible to have WS3750G-24PS in one stack with WS-C2960S-24PS? I want to add two new WS-C2960S-24PS to stack with one WS3750G 24PS.
View 1 Replies View RelatedCisco... Have two new 3750X switches (24P-L, and 48PF) trying to stack. Brought them up together a few weeks ago with the 24P using LANBase and the 48 IPBase. The expected happened. They saw each other in the stack ring, and the 24 port was excluded due to license miss match. This was corrected. Now both are IPBase.Now I have the two switches stacked, and boot the 48 and 24 at the same time. Monitoring the 48 I get a check message "FIPS: Flash key check: End, Not found. FIPS: Stacking Not Found". The 48 does confirm the stack cable is connected. This happens early in the boot process, before master election.OK.... Now looking at the 24 Port. After applying the new license, and actually booting successfully and few times. It will no longer load the boot file. Wants an environment variable. Going to have to dig into ancient history for that. Had to deal with that one about 8 years ago. Do not feel that is part of the stack disable issue though.

What is the procedure to change the flash (64MB to 256MB) on a 2811 router?
I can remove the flashcard when the router has already started, change the flashcard and load the new IOS?
I have a cisco 3750 swicth which i want to load a new ios to but unfortunately there's no enough space on the flash.

View 10 Replies View RelatedI gave one of my interfaces a IPv6 address the other day and now all of my servers have IPv6 addresses in that subnet.
I'm reading about "ipv6 nd suppress-ra" and I think that's what I need to disable but that's not a valid command on the 3750.
Is there a way to disable this 'automatic IP giving out' thing that I have going on?
This would probably sound like a stupid question but it took at least 2 hours of my time so far. I have a 3750 switch where a router and a server is connected. From the switch I can ping the router and server with no issue (directely connected). But from the server I am not able to ping the router. The router and the server are in the same subnet. The router is configured as the default router for the server. I am not able to ping the server from the router either. Here's the output of the ip route from the router. The server IP address is 10.1.200.21 and the router IP address is 10.10.200.1
10.0.0.0/8 is variably subnetted, 8 subnets, 3 masks

I have a bit of a mystery on my hands. I had a whole campus of Cisco 3750's cache a new default gateway. Example
Cisco3750#sh ip redirects Default gateway is 10.10.10.1
Host Gateway Last Use Total Uses Interface172.16.0.5 10.10.101.179 0:00 185749 Vlan1172.16.0.76 10.10.101.179 0:01 47254 Vlan1192.168.0.154 10.10.101.179 0:00 183090 Vlan1
My question is what generates a IP Redirect packet or how does the switch know what to change the gateway to? As in my case the changed gateway was a dead IP address. So I am at lose how this happened. I this case the Host IP's are network management servers conducting polling.
I have a 3750 at a branch running EIGRP connected to two routers that both have configured:
access-list 1 deny 0.0.0.0
access-list 1 permit any
access-list 2 permit 0.0.0.0
access-list 2 deny any
router eigrp 1distribute-list 1 out FastEthernet0/0distribute-list 2 in FastEthernet0/0
Due to this recently applied config the switch become unreachable from the outside and cannot ping anything. Everything connected to it works fine. I was able to remote into it from a switch behind it and noticed that the 3750 has no default route in the routing table. I do see a default route in the eigrp topology table. How to make the switch learn a default route maintaining the existing configuration on the routers.

Trying to copy the system image file from the sup-bootflash to a new 64MB ATA flash card. Yes the software can support the 64MB card.
The ATA flash card was formated successfully, however I cannot copy the system image to it so that it can boot after a power loss.
The command I tried was: console(enabled) copy sup-bootflash: slot0:
The source filename was typed in as shown in the Show Verison command.The result was: Error opening slot0: no such device.I suspect that I am missing something obvious as I am new to Cisco Switches.
We have a 3750 acting as the core. By default IGMP snooping is enabled on cisco 3750 from the documents.but, when we see the ip mroute table on the switch, it doesnt show any output.
View 40 Replies View RelatedI had setup a lan infrastructure with 5 3750 stack swithes. In these 3 of them are in one stack which is acting as access switch, 2 of them in another stack which is as core switch where all the SVI is configured. Now, when i tried to ping from our edge pc which is connected in access switch to default gaeway, which is configured in core switch, the ICMP is getting delayed . But when try to ping from the same edge pc to another user PC, it is getting less tahn 1 millisecond icmp replies.
why icmp is delaying to default gateway , but working with another edge to edge pcs without any delays?
We have a 6509 series of core switches and 3750 series of L2 switches, There is no default gateway or any static routes to any IP.VLAN 1 is made admin down and another vlan is used for all communication here in this environment
Attached is configuration for reference But still I am able to take telnet or SSH. I want to know how telnet or SSH or tacacs authentication happens without any static or default route.
i am facing a problem when the client vlan is commmunicating with the default gateway on the core 3750-x.
ios in 3750-x core is 3750e-universalk9-mz.150-2.SE.bin. But, client to client communication is happening without any dealy and icmp is less than 1 ms always.
When try to ping default gateway of client vlan, it is getting delayed (variable icmp delays). Is this an ios bug?
I recently configured a cisco 3750 switch for a stand alone network here at work, and on all our other switches and routers we use ACS to access everything. This switch being a stand alone I dont have that option.

I have a WS- C2924C-XL switch that I would like to upgrade the IOS version on. The IOS version in question can only be installled on an 8MB version of this switch, I have tried to confirm the amount of memory present in the device but I am getting conflicting values depending on where I look.The model number would indicate that this device is a 4MB version, therefore not compatable with the upgrade.Running the show version command from the CLI shows Processor having 8192K/1024K bytes of memory.Accessing the switch via the VMS management interface displays a value of 4MB.

View 5 Replies View RelatedEnd user have had problem with IP phones that are connected to 3750 stack; many times IP phones lose connection with CallManager and the only way to clear this issue is with clear arp command. DHCP for IP phones is configured in 3750 stack.
At the beginning 3750 stack was set a VTP server, and the others as VTP clients, we detected another VTP server switch so we thought that was the problem, but after removing the issue remains. Finally we set all switch in transparent mode.

1. There is no problem for using this tar file for all models?
2. I followig command is correct for the change I plann to do ?

We have 2 3750 24 port fiber switches in a stack and we would like to change the member to become the master. Both are running the same IOS and they are alive on the network. I read that you can change the who becomes the master by setting the priority number higher on the member, which we did. However this requires a reboot of the member to take effect. Is there a way to force this without having to reboot? One other note, both switches in stack have a single gig connection that goes to the core (6500). One gig link is blocked due to spanning-tree and this is on the member that we want to become the master.

I have three new 2960 switches as listed in the title. I configured them as follows:
192.168.1.215 host: whse-c
192.168.1.216 host: whse-b
192.168.1.217 host: whse-a
Switches B and C flow into A before continuing on into the server room switch (distance issues).All three switches are configured for ports 21-24 at 1000 and set as cisco switches. all other ports are undefined as they have a myriad of desktops, printers and non cisco access points flowing into them. side question - should i configure them as access points where applicable even if they are non cisco? I am replacing three netgear switches that currently are in place and have no known issues other than they are old and the fans may fail soon.hooked up .217. was able to get to it from the network. Hooked up 215 and then 216. All the sudden I lost the ability to tap into the switches, any of them. (I think I had done 215 at that point too, before adding 216. I found out later it took the network to its knees as internet was lost, and the MPLS stopped functioning.
I undid the changes and put the netgears back in service and all was right with the world again. At first I thought it was a bad host name as I had used whse-a on switch C in error. I changed that after this issue.Later that day I put 215 in place. checked it from the network and could get to it just fine. Then I put 216 in service. I lost connection to 215. I could no longer get to the internet from my pc and the MPLS went down again. This time I just unhooked 216. 215 is still in place and working on the network at the moment and not causing issues. (btw these switches are not even in my path from my pc to the internet, just on the same network) tomorrow I am going to try 217 again while 215 is still on the network and see if there are any issues adding that swtich. if I can do so, and there are no problems, is this an indication of a faulty switch? what further testing can I do, have I missed something in setup? If this brings the network down again, why cant i add two of these switches to each other/on the same network path (B and C were not even connected to each other yesterday evening when it went down again).

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?
