Feb 10, 2013We are using CISCO Catalyst 6500 switches as collapsed core/distribution switches (2 layer architecture). I want to connect approximatly 10 application servers to the network. Can I connect the servers directly to the catalyst 6500 switches using WS-X6148E-GE-TX line cards? The other option is to use access switchs and then connect the servers to the catalyst 6500 through access switch(Catalyst 3750).

Apr 13, 2013I have a 3750X four-switch stack acting as the core of a fairly simple LAN. All I need to achieve (and this seems inordinately hard, but it is entirely likely that I'm just being dense) is to get access to the internet through my core switch, through the firewall and out through my VSAT. I've spoken at some length with the firewall providers (Cyberoam) and they tell me all I need to do when I migrate onto my new system (Cyberoam is currently in place at the entrance to our existing LAN) is change the local IP address of the Firewall, plug in the new switch to the LAN port, and away I go. Tried that, didn't work, so obviously I'm missing something.

Jun 8, 2012connecting a 5548 pair to our core 6509s. Just want to be sure we don't introduce any issues into the network.The 6509's are connected and perform all the routing. Essentially, we're moving away from a 3750 stack in the data center and the 5548s are the replacement. We'd want to limit the vlans to the specific server network vlans. Our current setup is a port channel between the 3750 and each of the 2 6509s for redundancy. I'd like to use the same functionality when we connect the 5548's but I'm looking for what the config should look like to ensure no spanning tree loops are introduced and that it is configured optimally.

Jul 15, 2012At our site we have a 4510 core switch and 3750x switches in our IDFs. The 3750 switches are connected to the core via DOT1Q trunks in a server client setup. We are putting in an Informacast/Berbee server witch will send pages and text to the cisco phones. We also have 1 3750 switch connecting to the core via a layer 3 port channel. If we put the Informacast server on the phones vlan would I just need to enable ip pim sparse-dense mode on that vlan only and enable multicast routing, ip multicast routing?

Jan 24, 2013I have been working on redesign of our network which was very challenging but almost there.We have a limited budget of around £20k(32k Dollor) Max. The cabling has been done before my time and it is very messy and cheap so you can not do a proper cisco hierarchical model at all.I can not have multiple links from each access layer switch to the core/distribution and as a result i had to connect some access switches together to introduces redundancy in a nutshell,we have two buildings, main building which has the server room in it and the other building which is just bunch of office. i have introduced a partial mesh on the normal building and have tried to introduce full mesh on the main building .

Nov 18, 2011If I have two stackable switches one switch uplinks to one 6509 core switch and the other connection uplinks to another 6509 core switch, and also the other stackable switch does not connect to the core switches. Because I am using hsrp and also we are not using vss then one uplink to the core is not in used only ones is so then how does creating an etherchannel between does two uplinks to both core switches benefit me in anyway such as more bandwith and using both uplinks at the same time or I'm I wrong?

I have tried to get option 1 as well as option 2 to work, but I failed... I would be happy if either option 1 or 2 would work for me - I don't really care which one. In both cases, the problem seems to be that the dcs-930l cam cannot access the internet (but the cam itself works - I can view the livestream through the local network).

Apr 11, 2013I am trying to test (if possible) the idea of having 2 6509-E switches connected directly to each other while using VRF-lite (Sup 2T). The idea is to have 3-4 separate networks. For example Net-A, Net-B,Net-C, Net-D. There is no PE router*, just these two switches. Also, there sin't any other access layer switches. All users connect directly to the 6509-E's via switch 48 port switch blades.
Net-A and Net-B on separate VRF's, but able to talk to each other. Net-C and Net-D* on separate VRF's without being able to talk to any other. Net-D* will have a PE since it comes from an external network. This is something I would like to test in a lab environment, but I am not familiar with VRF's.
