4500 switch is connected to 2960 switch.
4500 config
Vlan 10
name Data
It has ip helper configured that points to DHCP.From 4500 switch port - port x connects to 2960 port.Port x is configured as trunk between 4500 and 2960.
2960 config
vlan 10
name data
All user ports are configured under vlan 10 and as access ports.Port x is trunk port connected frpm 2960 to 4500 switch allowing vlan 1 and 10 only.This switch has no default gateway configured.
We connected user PC on 2960 switchports and they were able to get the IP from DHCP server and were able to access the network? My question is how users on 2960 switch are able to access the network without ip default-gateway configured on 2960 switch?
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.

We have dlink dir320 router and cisco 877W.
The goal is to make a 877W to work as a wireless client of dlink dir320 and brigde the LAN&WLAN so than the LAN clients of 877W could take DHCP from Dlink 320 directly.

i am first time to trying to make Vlans. I managed to do 2 vlans to SA520 to ports 1 and 2. But when i try to separatethem to SG300 with web management it doesnt work. Vlan 1 works fine, i untagged wanted ports and forbid vlan 2 ports.In Vlan 2 there vice versa, is this right way to do? Both Vlans has their own DHCP range as i do them to SA520.
View 2 Replies View RelatedSituation: Currently WS-C3750G-48TS-(S or E) switches are on stack. Now these units will soon EOL on Jan. 30, 2013 and Cisco recommends that
WS-C3750X-48T-S or WS-C3750X-48T-E will be used.
The question is: Will the new SKU works together in a stack with the old ones? Will there be no changes on the type of stacking cable to be used?
how this switch module works in 2911 router? I have two 2911 routers in HSRP configuration for redundancy with crossover cable between switch modules. OSPF running on routers.If active router loses its power and then comes back again, it boots first, its internal link to switch module comes up and it starts to forward packets to switch module. The switch module starts to boot only after router is ready. So I have outage of about 3-4 minutes. For our real-time applications it is way too long.
any way to start booting of the switch module before router gets ready?I understand I can boot it manually, but it is only after router is ready. Only way to get around it I found is to disable internal link and use router interface to connect to the switch module.
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)
View 5 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?

No status lights turn on at any point (e.g. syst, xps...). 10g network module is installed with a 10g LRM SFP. All lights on the module are amber. However, it passes according to POST.

I know these are no longer supported, but I have to ready them for migration. Recently a problem began with these switches. What happens is that when I telnet to them, I cannot authenitcate via TACACS. This works fine for all our other IOS equipment, just not for these 2 switches. The error is:" % Error in authentication" and then I get kicked back to the login prompt.
The odd thing is that when I connect to the switch via the console port, I can authenticate fine with TACACS.

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]

View 2 Replies View RelatedWe 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.
