Cisco Switching/Routing :: 2960 Configuration From A HP 2510
Jan 17, 2012
At a college we have Ciscos 2960 and are trying to setup VLAN tagging and also using RST or MST. The traffic on the jack should get tagged vlan 248.We were told by the college that Ciscos in the labs will not work with the Alcatel switch that provides access to the lab. That Alcatel is in Bridge 1x1 mode. The college will not change the configuration on the Alcatel.We got the Ciscos to do VLAN tagging and can get network access. However the spanning- tree is not read properly. Cisco does not properly read the Alcatel's RSTP (since the Alcatel is doing tagging on the BPDUs). It places the root of the spanning tree under vlan1 instead of vlan248.
The college strongly recommends HP Procurves and we are using that as test.The following is the configuration on the HP and it works with no effort (it reads the spanning-tree information as MST)We will end up getting HPs instead, if the Cisco cannot work with the Alcatels.
I have a 24 port 2960-S that is not communicating with a 2960-LST that it is directly connected to over fiber. The link is up on the LST but will not come up on the -S. What command should I use to bring up this link? I have tried no shut from the (Config-if)# prompt.
In one location we have a HP 2510-48 port switch which we need to connect to a Cisco 3560 switch. The problem I have is that we have issues connecting fibre to the HP switch, so I have decided to attached a CAT 5 to Fibre convertor at this end and another to the cisco switch.
My question you can not connect a HP switch to a Cisco switch, is this true or do I just need to confirgure something on the ports.
I have a 2960 that bounced several times over the weekend and then appears to have lost its configuration. Using CDP from the backbone switch pulls up the information below. Is there any way for me to configure the downed switch from another switch on the network? I am trying to avoid having someone from the site try to find a console cable and a suitable computer with a serial port. [code]
Using Cisco 2960 series switches (Have 8 . 2 stacks of 4) to replace 6 old switches. 4 old switches had IP ranges of 192.168.6.*** and all new switches have 10.1.*.* addresses. Core switch has 10.1. as well as 192.168 ip addresses but i need to configure one vlan (5?) to route to 192.168 address. PC's on 10. address taking a long time to access 192 range.
I'm fairly new at trying to create isolated network segments on Cisco switches. What I'm trying to do is have multiple isolated paths that originate from my v Sphere infrastructure travel through a layer 2 link, v LAN, up to a MLS, and ultimately out to to the internet through a firewall. Each sub net might ultimately have a number of hosts on it, but I don't think the make up of those hosts will matter here.
My initial thought was creating v LAN tagged port groups on v Switches on my v Sphere infrastructure. Physical connections will go from my ESXi hosts to the 2900 series Cisco switch connected to trunk ports. Both v LANs would be configured on the switch but not assigned to physical ports. The physical connection to the 3750 would also be a trunk port connection from the 2960. The 3750 would have SVI's created that are attached to VRFs that would control route traffic. This might be totally wrong but from what i've read it seems to be going down the correct path I think.
Two part question, is this the best way to go about designing this network? If so I seem to be really struggling with the SVI/VRF part. Every time I create an SVI all of my hosts on the 10.10.10.x network can ping them, regardless of which v LAN they're on. I just cannot seem to isolate the 172 network.
We had core(4503), distribution(3750), and access switches(2960) in our environment. Currently we configured the clock manually in each switch, but a reboot of the switch resets the clock also. We are planning to make a single switch as a NTP servers and others are clients to synchronise the correct time even after a reboot of the access switches.
I was wondering if I can force catalyst 2960 to skip startup config stored in NVRAM and boot with no config everytime it is powered. I tried to find it on google and in cisco white papers but still no luck. I found only commands that begin with "set boot config-register ... ", but switch acts like it does not know these commands.
I am able to create above smartport macro on Catalyst 3760 & 6500, but not on 2960 & 3750 (see below):switch(config)#macro ? auto Macro autoexecution settings global Enter global macro configuration
I've recently purchased a Cisco catalyst 2960S-24TS-L & setup 3 V LANS 10 (no current IP),20 (192.168.2.1) and 30 (192.168.3.1) to reflect the router V LAN configuration & ip information. When connecting my PC to the switch to test connectivity on (2.1 & 3.1) I'm unable to connect to the the net but can successfully ping GW (int FE0.20 & FE0.30) 192.168.2.1 & 3.1.
The router is an Cisco 1801 & it seems this is where the configuration issue is but I'm unable to figure out how to complete the setup. It has been quite awhile since I've configured a Cisco router.
Ive never had this router connected to a switch so all router switch ports are in the default VLAN1 (192.168.1.2), with FE0 disabled. In trying to get the switch to communicate with the router I made the following router config modifications.
FE0 enabled with subinterfaces configured FE0.10-currently no ip FE0.20-192.168.2.1/27 FE0.30-192.168.3.1/27
I have two issues I want to resolve: 1) I do not know what additional steps are required to allow 2.1.& 3.1 V LANs to access the net. 2) I want to disable VLAN1 if possible & use the network IP for VLAN10 (192.168.1.0). I'm unsure how to do this as any change on VLAN1 immediately breaks router access and the router reconfiguration becomes more complicated with changes to the FW ACL etc.
I am going to creat VLANs very 1st time therefore for test purpose I have following simple scnerio.I have created 2 VLANs , VLAN2 and VLAN3 on Cisco Catalyst 2960 series switch. Ports 1-12 is assigned to VLAN2 and Ports 13-24 are assiged to VLAN3. Now I have configured DHCP on Microsoft Server 2003 defining 2 scopes with following configurations.
Scope 1 for VLAN 2--- Range is 172.16.0.17 to 172.16.0.30 with subnet mask=255.255.255.240 . Server IP address 172.16.0.17 ( Note: Address 172.16.0.17 is excluded from dhcp server Scope 1 and give to the MS server itself) Scope 2 for VLAN 3----Range is 172.16.0.33 to 172.16.0.46 with subnet mask=255.255.255.240 .
Now in Cisco 2960 series switches, under Vlan 2 and Vlan 3, I have following configurations...
interface Vlan2 ip address 172.16.0.30 255.255.255.240 ip helper-address 172.16.0.17 interface Vlan3 ip address 172.16.0.46 255.255.255.240 ip helper-address 172.16.0.17
Now the problem is when i connect a client computer to any port from 1-12, It gets correct IP address from Scope 1 but when I connect a computer to any port from 13-24, it does not get the ip address.
Further I want to do inter VLAN comunication as well for that purpose i Have an ISR 2900 series router. What further configuration i will have to do on router for inter vlan communication.
I have an existing stack of 4 x 2960-S switches connected by stack cables.I would like to add another 2960-S switch to the stack but am unable to as the 2960-S will only allow 4 x 2960-S switches per stack.how I would add the 5th 2960-S switch to the existing stack of 4 x 2960-S switches.
I am position to migrate from CatOS 6509 switch to native IOS 6509 switch. long time ago, there was some site to convert automatically based on copy and paste onto the tool, but i can not find.
Does anybody know how to convert CatOS configuration to Native IOS configuration ? It is not IOS change, but it is configuration convert.
My management has tasked me to give them a high level overview of the different switching we can choose for our new building.
This is what I know so far.4 Closets, each closet has 450 ports,One MDF room that is will contain one UCS Chassis and a Nimble iSCSI SAN.
I am working on the spreadsheet and it looks like this (Not totally filled):

I am using a 3750 as a default gateway for multiple Vlans on a few 2960 switches. The trunk lines are configured and working and I have assigned ip addresses to each of the Vlan interfaces on the 3750. My issue is that I can only ping the ip address on the Vlan interface of the 3750 if I have a working computer plugged directly into the Vlan on the 3750. I only have 3 vlans on the 3750 that have hosts directly connected (vlans 2, 10 and 40) the other vlans ( 20 and 70) don't have any clients plugged into them on the 3750 but the hosts reside on 2 different 2960s that connect via trunk ports. How do I keep the vlan interface on the 3750 switch pingable when I don't have hosts directly connected in that vlan on the 3750? (yes, I have enabled ip routing on the 3750)
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.
I'm having a strange problem where I'm not able to get through a Cisco 2960-S L2 switch when connected through vpn, while LAN-WAN traffic is working fine.The situation on site is the following:When inside the network I'm able to get to the internet without a problem. The problem is within a vpn-session. When this session is succesfully started I can ping and manage the Cisco 2960-S switch, but I can't ping or manage the Dell switch from my laptop. I can however ping the Dell from the Cisco-switch. [code]
This will be this configuration for all input interface right ? For the Output part I'm lost, what do I have to do ? And for the 2960-2 do I have to put the same configuration ?
I am having difficulties implementing Mac-auth on selected ports between an HP ProCurve 2510 and Cisco ACS 5.3.The 802.1x works just fine, but for selected ports I need to implement port-access with MAC-based authentication instead of regular 802.1X (yeah, I know, but this line of ProCurve switches only support one auth-mechanism per port!).The switch successfully forwards interesting MAC-auth requests for authentication to the ACS with CHAP/MD5, but the ACS reports this:
Logged At: April 16,2012 1:20:48.080 PM RADIUS Status: Authentication failed : 22056 Subject not found in the applicable identity store(s). NAS Failure: Username: 002655886b3d MAC/IP Address: 00-26-55-88-6b-3d Network Device:
[code].....
The ACS is configured to use the Internal Hosts database, where the client computer is configured like this;MAC-address: 00-26-55-88-6B-3D
I have a dell vostro 2510 vista.Am able to connect to internet wirelessly no problem but when i move laptop out of wireless range and plug in ethernet cord I cannot connect. Have 1394 net adapter and it tests ok with troubleshooting?
We recently updated a site2site link to metro ethernet, ISP call it 100mbps LAN Extension, but to me it is just QinQ over fibre connection. Most went well, one thing (annoying to me) is we can not ping our switches on both ends anymore.
We have a 3750 in headend and another 2960 on the other end. I used to be able to ping/telnet to the management IP from one to the other. Now we can not. I think the ISP is applying some configuration on ports of their customer-premises equipments (both are Cisco switches) but agent in ISP told me no. I thought there is some configuration on Cisco switch to block "MAC discovery" but i just can not remmenber what was that and google also failed me this time.
I have got two links from the same ISP, primary and secondary and connected to two different switch. The ISP have passed the trunk vlan of 30, 31 and 32 on both of the links. The ISP can't provide stp. I have got another managed 2960 series switch. How can I obtain failover on switch level.
I have IP phones connected to 2960 i want to segregate traffic traffic comming from IP phones which has a COS value of 5 and want to allocate a band width of 200 MBPS for those traffic .
Can any one share sample QOS configuration for achiving this in 2960 ?
Have Cisco catalyst 2960 IOS ver12.2(53)se2 when power on the power LED does not come up and on this is what shown on hyper terminal. what need to be done for this switch ?
Boot Sector Filesystem (bs) installed, fsid: 2 Base ethernet MAC Address: b4:d9:8d:27:4c:00 Xmodem file system is available. [code]......
Interrupt within 5 seconds to abort boot process. Boot process failed. The system is unable to boot automatically. The BOOT environment variable needs to be set to a boot able image.
I currently have a network with (8) 2960 Cisco Switches. (6) of the 2960 switches are etherchanneled back to (2) 2960 switches in the computer room. I would like to setup QOS on the (8) switches, however the traffic is very differnt on each of the switches. I have video, ip phone, server, printer, PC traffic. I am not sure what the best method of separating this traffic into differnt QOS queues.
I have an switch 2960 and i have made an SSH connection . But the problem is that whenever i try to open with my teraterm or putty it ask for username and after that password but does take the password. It shows an error of password what should be the problem.
