Cisco Switching/Routing :: 2960 Switch Ports Using POE?
Feb 5, 2013I have a statck of 4 2960s switches, with POE powered access points on 2 of them. All of the access points appear to be functioning normally. For some reason, on 3 interfaces connected to access points, I get the following when issuing show interfaces status:
Gi3/0/9 connected: T 7 a-full a-1000 10/100/1000BaseTX
^
My question is regarding the "T" in the status field. I can't find any documentation on this.

Aug 6, 2012I have two questions for a Cisco 2960 (WS-C2960-24TC-L)
1. I am working to setup a few Cisco 2960 switches for HP iLO access to our servers. We are going to segregate the iLO network (VLAN 40) from the data network (VLAN 10) by using a different VLAN. All of the HP servers will be configured with static addresses. My question is, how do I set all the ports to VLAN 40 so that untagged devices will automatically go onto VLAN 40? I don't want to have to configure the VLAN on each iLO port on the server. I tried to set the port to: "switchport trunk native vlan 40", but that didn't work.
2. Also, how do you access the web GUI for these switches? I get a login box, but putting in the enable password doesn't work. I have the following commands in the config: [code]
Cisco Switching/Routing :: 2960 Is Shutting 2 Ports Down On Network
Dec 27, 2011We have a 2960 switch which is connected to the core via a VLAN trunk. We have disabled broadcast port suppression but, the 2960 is shutting is shutting 2 ports down on the network and this looks like excessive braodcast. How and why would the switch start dropping traffic when the default is don't do anything? It had to be rebooted to get the port active again

Cisco Switching/Routing :: 2960 - Ports To Put In Trunk Mode

View 1 Replies View RelatedCisco Switching/Routing :: 2960 Storm Control On Trunk Ports
Feb 9, 2012We have around a dozen Catalyst 3560 and 2960 switches in a ring topology. We are considering adding storm control to our trunk ports. Up until now we have only used it on edge ports with default values and without error-disable.I am proposing that we also add storm control to trunk ports at a lower level and that we error-disable only the redundant links that make up our loops.
-storm-control broadcast level 25.00 20.00
-storm-control multicast level 2.00 1.00
-storm-control action shutdown [only on redundant links]
In a storm all links will restrict broadcast which should work accessing remote switches, but the redundant links should errdisable and block the redundant path. It is important that the action line is not applied to links that are not redundant as we could isolate parts of the network. Any reason not to use storm control on trunks?

Cisco Switching/Routing :: Catalyst 2960 Series Ports Disabled When Connecting Vmware
May 21, 2012I have a Cisco Catalyst 2960 series switch. When I connect another switch or a VMWare Esx server on one of the ports, the port blinks for few seconds and then goes off. When I connect a desktop or laptop or a windows server the ports stay led and I can access resources on the network. However, when connect another switch or a vmware esx server, the port is disabled.
What config in the switch can I check to make sure the ports stay on regardless when I connect a desktop / laptop, switch or vmware server?
Cisco Switching/Routing :: 2960 / Make Ether Channel On Switch 1 Which Has 24 Fast Ethernet Ports
Oct 8, 2012I have 4 cisco 2960 switches to which many users are connected. No vlans are the only default vlan 1 is there. Now I want to make ether channel on switch 1 whcih has 24 fast etherenet ports. Can I make port 1- 8 as one ether channel which are connected to users or i can only make ethere channel of ports that are connectd to other switchs. If I can, how the other switchs will comnicate with the switch ports bundalled in the ether channel in switch 1.

Cisco Switching/Routing :: InterVlan Routing With 3750 And 2960 Switches?
Nov 21, 2012I 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)
View 5 Replies View RelatedCisco Switching/Routing :: 2960 / SG 300 Switch - VoIP Setup - Asymmetric Routing Not Working
May 21, 2013I 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.

Cisco WAN :: 2960 / 2811 - Connecting 2 Ports With Two Switches
May 18, 2012I have a 2960 and a 2811 with a hwic card I have one port set as 100 meg and another port set at 10 meg. Both are set to access mode. i need one port for failover (10 meg) . I can't do ether channel on the hwic. How do I prevent a loop when I connect my second connection. While having both connections up. Should I use bpdu guard? the goal is to have one port fail over if the 100 meg goes down. And I'm currently running ospf so it should take the faster connection.

Feb 23, 2012We 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.
