i have a device connected to 2960 switch. It is an access port and i could ping the device from other switches , also from outside the lan. But i am not able to ping the device from 2960 switch alone. I suspected and checked the arp table and it was showing as incomplete. I created the manual arp entry and tried pinging but no luck.

I have a Cisco 2960-S Switch, It is connected to a jack in the building to check the settings, Interface VLAN 1 has an ip, there is a default gateway, Any host connected to switch can access the network resources. But the problem is that I have to use Serial Cable to configure it. I cant ping or telnet into it from any other device. PC's are on different subnets/VLANS.
Basically this switch is connected to a port in a different switch, Do i have to make a trunk?
I have 2 switches. 2960 and 3750. I have trunk on both ports of the switch. there are couple of vlans and ports are assigned to those vlans. examples are management, voice and data. int vlan 1 has ip there is default gateway the hosts are able to connect to the internet when connected to the switch.

It seems the difference between using my computer and the 2911 is that with my computer I am able to set the default gateway as the end node's ip.

The topology will be 2960 switch -> unmanageable Switch -> unmanageable -> PC connected
The issue I am facing most of the PC are getting IP addresses through DHCP server and very few 5 or 6 PC’s out are not getting the IP from DHCP server.If I switch of the switch and switch on the issue is resolved for those and it will raise for some other PC’s.
I have 2960 switch and i can't access it using my console cable .I can access other switches in my network ( 3560 & 2960 ) but i can't access only this switch.may be the console port in the switch damaged? or it's a bug ?? !!! although the switch is worked normally.

View 25 Replies View RelatedI have a /28 subnet between my internal and external firewalls for L3 connectivity. On our internal firewall, I have a default route for internet traffic pointing to the external firewall (10.10.1.2).
We will be inserting a web filter appliance as indicated on the diagram. The appliance requires an IP address to be assigned to the LAN interface.
What is the best way to accomplish this with minimal impact? Will my default route on my internal firewall have to change to the IP of the web appliance if I address the web appliance on the 10.10.1.x subnet?Should I address the web appliance on the 10.10.1.x subnet to begin with, or create a vlan on the 2960 and a L2 interface on one of the firewalls?

View 1 Replies View RelatedI 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.
Does the Model "WS-C2960-24PC-L" Supports IP Routing or not?

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.

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.
I am setting up a new 2960-S switch and none of the recommended username and passwords combinations work. I have tried CIsco Cisco, <blank> cisco and various other permutations.
I have tried to reset the switch to factory defaults and it still doesn't work. The switch is currently connected to a 3560G and has been assigned an IP. If I try to access it from Network assistant it shows as unmanaged and I get prompted for a username and password.The switch is connected to another new 2960-S via a FlowStack module.
I need to know the 172cisco 1 router support to IPv6 & it support to IPv6 then which IOS is required for it.Also I need to know the cisco 2960 switch is support to IPv6?

I can understand it 's one of those very basic questions , but how do I identify a Switch is Layer 2 or Layer 3 ?Looking through # show version command and checking the IOS version to be IP BASE or LAN BASE . Is it the right way ?Cisco 2960 is a Layer 2 or a Layer 3 Switch ? I noticed that access-lists could be configured which means that it 's a Layer 3 Switch , right?

View 6 Replies View RelatedDocument at url... is quite interesting,One of these goes about the behavior of a switch (2960-S and 3750G) when QoS is not enabled vs the one when QoS is simply enabled with "mls qos".What additional commands, beside "mls qos", would be needed so as to simulate as accurately as possible the switch's behavior when QoS is not enabled?
