I have a 3com 2948 switch and is needing to put the configuration on a Cisco WS C2960 48 port switch. I am attaching the config to heck if that is correct. I know my IP will need to change to .123
View 7 RepliesSwitch A is: WS-C2960-48TC-S
Switch B is: SG 300-10MP
Neither switch supports a similiar transceiver module. We are looking at transceiver GLC-SX-MM for Switch A, and MGBSX1 for Switch B all the Layer-1 information (SX / wavelength, Multi Mode, etc.) I am able to find out about the two transceivers seems to match, so would there be any issue by having these 2 "different" transceivers at either end?
i have new project in hospital with the bellow product :

i need to configure this switch in order to work first the 2 core switch for redundancy then each catalyst switch 2960 connected to the core with 2 uplink each uplink for each core switch that way i have rendundancy in the connection then i need one vlan ?i need to configure this switch to work perfectly with each other in best redundancy mode?
i had made a software upgarde on the switch 2960G series have no any passwords, when I fished the upgrade process after rebooting the device i found it need a UserPw to access device manager. i tried to use the default PW "cisco" but it dosen't work too.. after that i tried the password recovery process to rest the PW, but noway, but now i have addition problem, when i try the cmd orders "flash_init , load_helper , dir flash" to beginning the password recovery process it shows the following:
The system has been interrupted prior to initializing theflash filesystem. The following commands will initializethe flash filesystem, and finish loading the operatingsystem software:

After that the problem updated
because I tried to install the IOS by Xmodem to reload the missing flash file.After finsh the TAR file loading and reboot the switch.......the LEDs of mode and Giga ports are lighted amber and not blinking, i tried many times to follow the steps to connect the switch by the emulator and consol cable by holding mode button and connecting the power cable at same time the device does not work, the switch now still not blinking, now i try to read and understand how can i remove the corrupted files and install a new IOS for this switch?What shall i do.
Customer has a Catalyst WS-C2960-48PST-L. and in some ports we have VoIP phones with PoE company Aastra. If I use first config we have problem when phone boot up.
First config:
description tp-11-voip
switchport access vlan 250
switchport mode access
switchport voice vlan 201
switchport port-security maximum 2
switchport port-security(code )
The MAC shown here is from a voip Phone. After the phone boot up, the p, because it must boot first in vlan 250 (access vlan). On the port you can only see the MAC from vlan 201. With the second config the phone can boot without problems:
interface FastEthernet0/48
description tp-11-voip
switchport access vlan 250
switchport mode access
switchport voice vlan 201
is there a reason, why it is the problem with the first config on cat2960 ? The same first config works with an Cat2950 without problems.
I would like to ask you that how can i know detail P/N on switch WS-C2960-24PC-S I want to know detail what is PC-S and some swith LC-S

There is a mistake with settings?
I have a C2960-24TT-L Switch with the following problem:When the Power Cord is plugged in the Switch, all switch indicator LEDs go on very briefly. Then SYST LED blinks very briefly, goes on steady and remains at this state without any indication at the console.Tried the reset by holding the MODE button while plugging in power but I still get no indication at the console. All is fine with console, meaning that if I take out the cable and plug it in another switch, then I see all that there is there to be seen.My question: Is the switch beyond repair or is there something that can be done to get the switch to run POST and boot at rommon so that I can reload SW and configs?
View 3 Replies View RelatedI've got a C2960 (sw01) and a C2948. (sw02) The sw02 switch is trunked with sw01, and is meant to serve as an extension to the VLANs (1-4) that exist on sw01. It is trunking properly, however, how would I go about giving the sw02 an IP so that I can access it via SSH? Would I have to create a VLAN specifically on sw02 with an ip and switchport an interface to use it? I know that a VLAN can only have a single IP, but I'd like sw02 to have an IP on VLAN1 (192.168.1.0 subnet), is that possible?

Unfortunately this doesn't work as expected, every connection attempt is resetted.We did a trace of the ssh connection attempt where you can see that there is some problem in the algorithm negotiation (see attachment).

View 4 Replies View RelatedI am a recent student to Cisco products and I have purchased some (what I thought was good) lab equipment to learn with on a budget. What I have is a 2948G switch and a 2620 router. My issue is this: the router has only one fast Ethernet port. Is it possible to use V LAN's and V LAN Interfaces on the router and switch to somehow emulate a second interface to connect to a WAN or sub net?

View 6 Replies View RelatedHave two switches configured and running 2 links to each other that are in a port channel. Now, I cannot get the 1 of the ports (Gi1/0/50) to come up at all, I've had the cable tested and replaced SFPs both ends. Switch A is a WS-C3750G-48TS and I believe the problem could be here, the last for GBIC ports, 2 of them we are using as links to Switch B in a port channel. Here is the config for both and the 'show int status' for both.
View 8 Replies View RelatedI am having an issue with LAG configuration on a Cisco SG300 52 switch. I have connected four Ge ports on the switch to the four NICs of a Dell R710 Server on which I installed Windows Server 2008 R2. Without LAG configured, these ports would forward traffic to and from the Dell server fine.However, if I configure LAG on the ports with LACP enabled, then they would not forward any network traffic. Debugging shows that the ports are up but their forwarding status show N/A. Am I missing any configuration? Can I configure LAG on edgeports?

There will be an ip address assigned to each vlan on the 4500 switch but there can not be routing enabled between the vlans on the switch.
View 2 Replies View RelatedI am writting in response to MAB issue which I noticed a few days ago and I am still not able to undestand what exactly happend. First of all I would like to say that I configured MAB authentication and according to the MAC the ISE configure a VLAN. All worked well: the test computer can change VLAN based on its MAC. The problem appear when I cut the connection to ISE server. Accourding to configuration the switch authorize the new device to VLAN 11 (critical VLAN) That is fine ! When the ISE server is up again I had a configuration which should reauthorize all ports assign in critical VLAN. But why that is not happend ??? It looks as the switch didn't notice that the RADIUS (ISE) was up and working again. [code]
View 1 Replies View RelatedI just started configuring my cisco catalyst 2950 switch. Basically im preparing for my CCENT exams my basic configuration is as follows.
-My Laptop is connected to the console port
-I'm connected to the internet via my wireless
-I'm connected to the switch port via my NIC card
im trying to move the config from an 3750 to 3750 PoE but without using the PoE options.I have allready download the config with tftp and upload it to the 3750 PoE. Now the new config is stored on the PoE switch but some of the old setting are still there. Not sure why, i think the config only overwrite the settings which are in the conf file and the setting which are not in the conf file but enabled on it will stay on the switch.After the upload of the config file I deleted all the config I do not need by hand.They are some settings i can't delete and I don't know why, this are the sittings:
1. each fastethernet port has this option: "no cdp enabled" this entry was no availble on the old switch, is the any possiblity to remove this entry?
2. the same for "no mls qos rewrite ip dscp"
3 and for this one "vlan internal allocation policy ascending"
The access swtich is a Cisco 3750 and the Core switch is a Nexus 5000 series. I am configuring the switchport were the AP (3502) and WLC (5508) is connected below:
For AP: interface GigabitEthernetX/XX
switchport access vlan 244
switchport mode access
[Code]....
The WLC is connected to the Nexus switch and it is not accepting the 'mls qos trust cos' command.
We are using 3750 switches as WAN router facing the WAN cloud. To configure QoS for its WAN port, should I use 'auto qos voip trust" or treat it like a router port and configure class-maps, policy-maps, and attact service-policy input or output?
Because switches have different queuing and dropping methods than routers, auto qos can generate QoS configs that are considered most appropriate for 3750 switches. However the switch functions as WAN router. Maybe it should be configured using router type of QoS with policy-maps and service-policy?
