- Catalyst 3750
Interface VLAN182
IP Address 10.62.182.254 255.255.255.0
Interface G0/2
Description Finger Print Server
Switchport mode access
[code]....
Here are the problem,If i connect Finger Print Device to port catalyst 2960, some device not sending data to server, but if i connect all Finger Print to HUB and from HUB connect to Catalyst 2960 at port F0/5, All Device(Finger Print) can send data to server...Is there any special configuration in catalyst so all device can direct connect to port catalyst 2960 without HUB?
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 3 VLANs here that need to be on the same network segment. They are going to be used by our Wi-Fi network (with Aironet APs), bound to 3 different SSIDs (as Aironet APs doesnt allow multiple SSID per VLAN), each one with a different authentication method and server.Is there a way to bridge those VLANs together with a Catalyst 3750 switch? I tryed configuring an IP address on one of the VLAN interfaces, then configuring a bridge with the vlan-bridge protocol (Catalyst 3750 doesnt have the "ieee" bridge protocol type) and put all 3 VLAN interfaces on the same bridge-group, but it didnt work (even with "bridge x route ip").I also tryed configuring IRB bridging, with the 3 VLAN interfaces on the same bridge-group and an IP address on the BVI interface (the way I used to do with old 2600 routers). Same result.(actually, I didint test to see if the interfaces are actually being "bridged", but I see neither of them can reach the router)
I have installed a Catalyst 2960-S and a 3750-X-12S and I am trying to setup a VLAN 51 for some VoIP phones. I have added the VLAN as an interface on both switches, but the 3750 is not showing VLAN 51 as active when i do a show vlan. Also, it omitts showing Gi1/0/1 & Gi1/0/3 which are uplinks to 2960-S switches plugged in and working on VLAN1.
Catalyst3750SFP#show vlan VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Gi1/0/2, Gi1/0/4, Gi1/0/5
My architecture is the same as show on the link with some difference.I use the router 1841 for inetrnet connexion instead of 7200VXR, this router 1841 is connected on the catalyst 3750 port G1/0/1.I use catalyst 2960 instead of catalyst 2950 or 2948.I use ASA 5510 for conexion on remote branche(I have 5 remote site), This ASA is connected on the catalyst 3750 port G1/0/37
Result of the test:
-I can ping devices in the same Vlans -I can ping devices in different VLANs -I can ping all device from the catalyst 3750
I cannot ping the router 1841 or ASA 5510 from the any devices (computer)The gateway of each computer is the correpondant VLAN IP address configured on the catalyst 3750.Why I cannot ping the router 1841 or ASA 5510 from the any devices (computer)
i have a catalyst 3750, in this switch i have 3 vlan, i need to secure trafic between vlans but im confused ,should i use ACL or VACL to secure ?which is the best ?if i use ACL to secure and limit ports between vlan, which is the best practice to apply the acl ( on th inside or outside of interface)
I have a network with a Catalyst 3750 as the main switch and then some Catalyst 2960 switches that are plugged in to that. I have a server running windows server 2008 with a couple of virtual machines running in Hyper-V. I created 4 VLANS listed below and gave the 3750 the following IP Address.I would like the 3750 to only be configurable from VLAN 40 but currently every VLAN can connect to it, I noticed in the standard web page settings there was a setting for "Management VLAN" but it was set to 1 and would not let me change it, I kinda assumed that was for the management port in the back.-Now the tricky part, I was trying to set up routing between the VLANs and so far I have only been able to get a sort of "all or nothing" routing to work. I can turn IP routing on and add two or more VLANs to the routing and it works fine. But what I was hoping to do is create a couple of "junction vlans" that would only route to one or two other vlans. For instance, I wanted to create a VLAN 100 that routed to VLAN 20 and 30 but nothing else. I also want to route VLAN 1 just to VLAN 30, and so on. I am able to do each one of the cases but only one, it seems like the switch only supports one "routing table" am I missing something or is this just a limitation of the switch?
I have a network with several catalyst 2960 switches and one catalyst 3750. I have created two VLAN and set up the proper routing and everything is working fine there. I have a client/server application that used multicast in the initial start up for the client to determine available servers, the issue is one of my clients is on a different VLAN then the server. I am able to route the multicast using MVR as long as both the server and the client are plugged into the 3750 by creating a static route, making the server a source port and the client a receive port. Unfortunately I need the client and the server plugged in to different 2960s. My question is how do I establish multicast routing between the two and perferably do it dynamically (always route multicast traffic from one VLAN to another).
I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net.
My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20
I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to (vlan2)my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to go out to the internet. I think it has to do with the routes. [code]
I am trying to setup a network using Cisco 2960 switches with vlans configured. One vlan will handle video coming from four cameras that are connected to another 2960.
We have four cameras feeeding one port each on a 2960, that 2960 in turn feeds one port on the main 2960 which is the video vlan for that site. From the site it goes back to a Cisco 3750 to be sent over to a Sonicwall firewall. If we connect to the 2960 that the camera are connected to we can see the video, but not on the main site 2960.
|_voip PBX___|-----|__3650___|------fiber-------------|__3650_____|------|_voipphone__| I have a case where voipphone is registered on the voippbx but peaple on both end can't hear each other . No ACL on both 3650 , no firewalls between them , distance is about 2 miles . I tried to make telnet x.x.x.x 1720 or 1719 or 1721 (h323 ports) to opposite switch -connection refused . How can test if ports are open on the 3650 ? Is it coorect If I create allowing acl and apply it on both 3650 on the interfaces connected one switch to voippbx "IN" , second switch on the interf connected to voipphone "IN" ?
but on interface gi 1/0/1 i want to have data from vlan 10 tagged as VLAN 20. At this time i have solved this issue very primitively
I have set up gi 1/0/2 as int mode acces, acces vlan 20 and i have connected gi 1/0/2 with gi 1/0/3 with eth cable. int gi 1/0/3 is switchpor mode acces, switchport acces vlan 10
How can i add two data vlans on cisco 2960 on one interfase? i have 3 mac adresses on one interfase: one PC, one ipphone and one XP virtual machine(VM). PC and VM are in one data vlan and phone is in voice vlan. i need to place the VM in another data vlan is it possible? if so could you give me a link or place information here.
I have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)
SITE A - Cisco 3750 L3 - VLAN ID 50 10.10.50.0/24
SITE B - Cisco 3750 L3 - VLAN ID 50 10.20.50.0/24
I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.
We have a low bandwith (15-20 Mbit/s) to the ASA from our Client vlan. If i connect the Client to the same vlan as the ASA is, the bandwith (90 Mbit/s) is good.
And we have following error message in the log from the switch:
%PLATFORM_UCAST-4-PREFIX:
One or more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded I first get the idea that the switch is overloaded with router traffic. Thats why i assuming i have to check the sdm templates, but i'm not sure if this resolves the issue.
Multicast is not working between our two datacenter, we have catalyst 2960S (two stacked) as the internal lan switch, and catalyst 3560E as the external switch, same configuration for both datacenters.The two sites are connected using metro, the external switch (3560) is doing qinq and encapsulate the data from the internal switch with the metro vlan (611).
IGMP snooping is disabled for all switches, although we prefer to enable it for the internal switches.For each datacenter there is a different firewall which also act as the router, we are using fortigate as the firewall.Following is the important configuration section:
Port 43 in the internal switch is connected to the external switch (both sites):
I have Catalyst 2960 S (WS-C2960S-48FPS-L) Switch. I have plugged in SFP module but still interface is down and line protocol down. Is there any configuration to enable SFP module and make the interface up?
i try to implement layer 2 qos in 2960. when i complete to configure the switch, i want to test the qos.PC1 conect to switch port 1,PC2 conect to switch port 2 . PC1 is source teminal. i use skydata.exe and FTP for the test.
when use the skydata ,the PC2 speed can reach 10mbps.when use the FTP , the PC2 only can reach 1.2mbps. why?
I can use Putty to SSH into my new switch (Directly connected to my laptop with ethernet cable), but I cant log into my switch.
Sent username "admin" admin@192.168.251.1's password: Access denied
It doesnt like my password, but I have only set 1 password (king) on this switch. I've configured 3 other switches with SSH and had no problem. Been trouble shooting for awhile and It'd be great if I could have a 2nd set of eyes take a peek, Also, my running config is attached.
How would I go about stacking 4 Cisco Catalyst 2960-48PST-L switches? The one switch needs to accept a fiber connection from a distribution switch. Do I have to buy flexstack module and cables? If so where does the module go on the switch? If this switch cannot do this set up, any other switch I should look at.
I need to upgrade a Catalyst IOS, but I got a bit confused. The catalyst is currently running "c2960-lanbase-mz.122-35.SE5.bin", but I want to upgrade to "c2960-lanbasek9-mz.122-35.SE5.bin", in order to enable ssh. [code] What are the appropriate steps in order to upgrade to "c2960-lanbasek9-mz. 122- 35. SE5.bin". I have downloaded the tar file (c2960-lanbasek9-tar.122-35.SE5.tar)
1) Do I have to delete the old directory (drwx 192 Mar 1 1993 02:07:21 +02:00 c2960-lanbase-mz.122-35.SE5)? 2) Are these the correct steps to download and extract the IOS? 3) Where will the tar files be extracted? Will an new directory be made or do I have to make one manually?
I have packet loss with QoS configured and I was wondering is it somehow connected with the QoS configured on the switch.The traffic is passing through fa0/19 and gi0/1 interfaces.
I have 4 Catalyst 2960 connected via Etherchannel to each other. If I plug in my notebook in one port, I see the traffic from the neighbor port. So my switch acts like a hub.. I had a look at my MAC table and saw it isn't full.
I have a Catalyst 2960-S switch and a pre-standard IP Phone (Cisco 7960). When I connect the phone to the switch the switch recognizes the phone and supplies power. I would like to prevent this behaviour. ie. I would like to disable detection of pre-standard equipment. Is there a command I can issue on the 2960-S to do this? For example, on a switch from a different vendor I can issue the command: no power pre-std-detect to prevent it from detecting the 7960 phone, is there an equivalent command on the Catalyst 2960-S ?
I have two 2960's in this new environment that I am administering. I am receiving a message on one unit (Designate it 2960-2) of %IP-4-DUPADDR: Duplicate address 192.168.168.8 on Vlan1, sourced by 3037.a63e.540. The "sourced by" address is the 2960-1. I do not know how these units were originally set up. How can I determine where the duplicate address is originating from.When I perform an ARP -a the address that corresponds to the 192.168.168.8 is the mac address of the ethersvi interface on the 2960-1. I
I followed the 3-switch Redundant stacking diagram and now when I boot up the stack Switch 2 is acutally Member 3 and Switch 3 is Member 2.
We plan on having Port-Channels spanning across Switch 1 - Master and Switch 2 (Member 3) of identical port types. Switch 3 (Member 2) is going to have 2 10GIG port channel created.
Is there going to be a problem renumbering the stack as they physically sit or should I just configure the devices based on thier logical member numbers.
I have CISCO RPS 600 (PWR-AC-RPS) is it support Catalyst 2960 and 3560 ? and which type of cable require since i have cable 22-18 pin and on my switch require 22-14 pin.
