I need to configure a Cisco 2960 switch as a DHCP server. The current IP address will be on a different seed than the DHCP addresses. i.e.
Switch IP = 10.1.2.3, GW = 10.1.2.1, Subnet = 255.255.255.0 DHCP addresses would be 192.168.1.1 - 200, GW=???? (10.1.2.3?) and subnet would be 255.255.255.0
I am trying to create a backup of my 2620 router so I can use for GNS3.
I have only configured the IP address on my FastEthernet port. Having many issues with no connection to my pc, finally I found that you must enable the interface 'no shutdown'. Now I have a valid connection
I have made no other configurations on this router, everything else is default.
I can successfully PING from both ends
**PROBLEM: My problem is that when trying to 'copy flash' to my TFTP server, the response is**
I have a 3550 switch that I am trying to upgrade the IOS on.I am trying to copy to a TFTP server.I am receiving a socket error.I saw that this can be fixed with
Switch#config t Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#no service config Switch(config)#exit Switch# 00:13:47: %SYS-5-CONFIG_I: Configured from console by console Switch#reload
I have done this 3 times to no avail.My TFTPd32 server on my pc is working fine.Here is the error
Switch#sh flas Directory of flash:/ 2 -rwx 556 Mar 1 1993 00:33:53 +00:00 vlan.dat 4 -rwx 3775 Mar 1 1993 00:37:54 +00:00 config.text 5 -rwx 24 Mar 1 1993 00:37:54 +00:00 private-config.text 6 -rwx 5687963 Mar 16 2007 01:05:23 +00:00 c3550-ipbasek9-mz.122-25.SEB4.bin 8 drwx 192 Mar 1 1993 00:04:40 +00:00 c3550-i9q3l2-mz.121-22.EA1a
I recently posted this same issue the other day, using TFTPd32. Now i am pretty close to fixing it. I do have a different setup; my pc ethernet port is broken so I am using an ethernet/usb adapter. I am attempting to backup my IOS from a 3550 switch to my PC.
I have 4506e core switch to which 10 other 2960 switches are connected.I want to upgrade thier IOS. how can upgrade it, can I upgrade it one by one or all at a time?
How do i go about setting up a TFTP server from laptop to Cisco ws-C3750 48P Switch, I need to pull the image off the switch and place it on an other switch that has a corrupt image, The switch which is corrupted is the same as above Cisco ws-C3750 48P.
I have been looking at grading the IOS version on our 6509-E however there is not enough space on disk:0 to upgrade to the version I need to install. The question I would like to ask is - is it possible to boot the IOS from a TFTP server? If this is possible what configuration do I need on the 6509 to enable this. How does the 6509 know about the TFTP server as an IOS is not installed and therefore it will not have a network configuration
I'm having some problems when upgrading the IOS of my Catalyst 3750 switch through a tftp server. I've been surfing the net and found that there seems to be a problem when the image file is larger than 16M but this is not my case.I erased the flash to be sure that there was enough memory space to upload the image but didnt work.I also tried with archive download-sw /overwrite command and using a ftp server but the problem is the always the same: [code]To make sure it was not a problem of my computer or tftp server, I tried with a different computer and with a different tftp server but the same happen. I also tried with a 3750V2 and still the same. Even when trying to backup the current IOS to my computer, I got "error writing".
Then, I have tried to do the same with a different model of switch, a WS-C3560-48PS and it works perfect.I still need to try using Xmodem but Xmodem takes ages to finalize the process.
I upgraded IOS-XE on 4500E (SUP7L-E) to cat4500e-universalk9.SPA.03.03.00.SG.151-1. I encounter the log when i try to issue write mem commad % VRF table-id 0 not activeCompressed configuration from 8947 bytes to 2140 bytes[OK].
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. This means that i need to backup the cureent (old) ios to my tftp server but the command keeps failing. It always gives 'No such file or directory' error .The free space on the flash is 8mb and my new ios is about 11mb.I also went inside the directory where the old is and inputed the same copy command but to no avail.Below are some of the command failure on the swicth:
I am looking at upgrading my 6503-E switch. While I get the chance, I would like all aspects upgraded as I finally have some "downtime". I am running a Sup 720-3B.From what I understand, the boot image is a recovery image (mini IOS) - should the main IOS fail.Where should this be installed, sup-bootflash:/ or bootflash:/ ?,The file is “s72033-boot-mz.122-33.SXI11.bin.”The Boot Loader. My understanding is that Bootloaders are not used in these Sups with a MSFC3? I am not sure why TBH .. but would this be the case ?Rommon can be upgraded. I don’t quite understand if there are two ROMs (SP and RP).
I have a Catalyst 4510 that is running IOS version 15.X that has a bug and Cisco recommends upgrading the IOS. Are there additional steps required to perform an IOS upgrade due to licencing Cisco put in place?
a) I have three C3750-X switch stack together as my SAN switch and running on the new 15.0 release which is 15.0(1) SE.
b) Recently the master switch rebooted without any explanation. Create ticket with TAC and got an answer that it is due to a bug with ID: CSCtr31957.
My question is, which release that should i choose either the 15.0(1) SE3 or the latest 15.0(2)? Will it affect any of my configuration if i change to 15.0(2)?
Finally, what is the best practice to upgrade IOS in a stack whether to upgrade it 1 switch at a time or do it to all at once?
is there a document that explains the compatibility of 3750 series that can be stacked together? for example can we stack 3750-x with 3750-v2 without the power sharing? Can we stack a L3 3750 with L2 3750 without upgrading the L2 switch IOS to ip services?
I wan to migrate from a router 2800 to L3 switch 3750G , the thing is that we have several vlans and we use a router sometimes with each interface configure with correspoinding vlan subnet ip to route traffic between vlans there is no static or dynamic routing only directly connected interfaces on router routing traffic to each other ?How would i configure a L3 switch interface for simillar functionality , below is my current router configuration
! ip domain name yourdomain.com multilink bundle-name authenticated ! vtp mode transparent
I recently upgraded a remote site of mine to IOS 15-2.SE ipbasek9 on 3 3560E series switches. On switch number 2 I have 5 VG224's running (vg224-i6k9s- m) 12.4(22)T3. After the switches reloaded the VG224's dropped their connection. After doing all basic troubleshooting I reloaded the 12.2 (58)SE2 ipbasek9 image back on to the 3560E's and the VG224's reconnected immediately after reload and all phones registered.
Is the problem a licensing issue with the 15.x IOS on the 3560's or do I need to upgrade the VG224's to IOS 15.x as well for them to connect and operate via the 3560e switch running 15-2?
I upgraded the newest IOS 15.0(1)SE for our SW C2960-24-TT-L, the process was succeseful. However, we found SW memory utilization raised to 82% this morning in normal situation. (Momery: Total 21341260, Used17471692) Did you guys meet the same problem after upgrading to 15.0(1)SE? I also would like to know what the normal memory utilization is? and what is the impact of memory utilization highly?
I was upgrading the newest software images on a c2950G switch. So i followed the step by step procedures from url...I removed the current flash that was on the switch and then for some reason typed reload. This started the switch up without the IOS. Make a long story short I am now stuck in switch: prompt mode and I am unable to use x-modem to transfer the newest IOS onto the switch. I am currently getting "no response remote system".
I am looking to simply monitor Port-Security , Error-Disable and HSRP. I would like to receive an email when any of these are triggered.
Port Security - Port Is shut down Err-Disable - Port goes into err-disable state (securedown) HSRP - When HSRP standyby changes are detected
I need to receive emails with any of the able are triggered. What is the easiest way to do this? I know SNMP is the main option but I have never worked with SNMP and dont understand it too much.
I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.
