Jan 26, 2012i'm already has one internet connection is connecting directly to the Core Switch 6509,Vlan 500 (1921.168.1.0) and the Switch is route any internet request with default route:
SW6509-conf)# ip route 0.0.0.0 0.0.0.0 10.170.10.10
10.170.10.10 is --> Next hop for the DSL router internal IP, and it's working fine.
The Problem: We have a new internet connection with new Vlan 600 (172.16.1.0) another ISP/ with another DSL router, so i need your kindly support and suggest how to connect both of them to exit from the Core Switch 6509. is it ok if i make another default route to the Next hop to the new DSL router as:
SW6509-conf)# ip route 0.0.0.0 0.0.0.0 10.80.10.10
10.80.10.10 is --> Next hop for the new DSL router internal IP.
is there any way like default route , route-map or any other features to :
route Vlan 500 (192.168.1.0) to exit from DSL 1 --> 10.170.10.10
route Vlan 600 (172.16.1.0) to exit from DSL 2 --> 10.80.10.10
Cisco Switching/Routing :: 4507 - Monitoring All Traffic From VLAN To Cloud
Jun 14, 2012I have a requirement to monitor all traffic going from the internal LAN to the cloud. The LAN is a layer 2 VLAN which spans multiple Cisco 4507 switched and other smaller switches.
The VLAN has an IP address which the hosts use as the default gateway.
The exit port is on a Cisco 3600X switch connecrted to 4507 #1 via a 10G fiber link. 4507 #1 connects the rest of the LAN. Those switches interconnect via 10G fiber and 1G copper links.
Currently the monitor host is connected to a 1G copper port, configured as a monitor port, on one of the backside 4507s The switch manager says he has the switches configured so that I can see all traffic on the VLAN.

Cisco Wireless :: WLC5508 Link To Switch Core Down?
May 16, 2012I tried to implement WLC5508 in my network but when I came to connect it to the switch core which is a Catalyst 4000 the link didn't get up.

If that might be the cause, is it possible to get WLC to 100 Mbps?

View 7 Replies View RelatedCisco Switching/Routing :: 2960G Core Switch For 400 Users
Jun 7, 2012I'm trying to decide what switch to use as a core for 500 users. I'm currently looking at either 2 x 3750X stacks or 2 x 4500s with dual SUPs and PSUs, both options will provide the number of switchports required without the need for additonal access layer swiches. Which switch option is best to go for here? All of our services will be located in our data centre which will be connected using 2 1000Mbps MPLS circuits. I wont need any advanced L3 features and we are not likley to scale over 450 users. Also is it ok to use the dual switch stacks or chassis to provide the collapsed core/access layer or is it best to have a dedicated core (using one of the above options with less switchports) and having a dedicated accesss layer using 2960Gs for example. Our structured cabling terminates in a single comms room so we wont need to distribute switches throughout the office.

Cisco :: LMS 4.0 Manually Added Core 3750 Switch Into System
Jun 25, 2011I am doing an evaluation of LMS 4.0. I have loaded the system on Windows and manually added my core 3750 switch into the system. Device availability is showing the device as available. However, the other pollers like link utilization, error count, etc. all show that there is no data. When I go into the poller config, the pollers for link utilization and errors show 0 devices associated and a status of "instance not found". The CPU and availability pollers show active with my one device added. I have verified the credentials and if I go into Inventory -> Port and module and select my 3750 I do get a list of all the interfaces and the descriptions so LMS is connecting to the switch and pulling data.
So how do I get the pollers for link utilization and errors to start populating data?
Second question, during install I did configure the software update section and it said there was an LMS 4.0.1 available which I told it to download. Now I have a psu_download directory and some more directories like cm, cmf, etc. but I don't see any file on what to do with them. What do I need to do to install the new package files that were downlaoded to psu_download?
Cisco WAN :: Multicast On 4510 Core Switch And 3750x IDF Switches
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?

View 2 Replies View RelatedCisco Switching/Routing :: 3750 - Extending VLAN To Remote Switch That Already Has VLAN ID In Use
Jan 10, 2013I 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.
Cisco :: Can't Have Multiple Links From Each Access Layer Switch To Core / Distribution
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 .

Cisco Switching/Routing :: 2960S Unable To Connect To Core Switch
Sep 21, 2012I have a problem with extending the LAN on a client site . They are looking to extend the LAN with a 2960S-series switch. Already in place is a 4510 switch which the 2960 is connected to via fibre. The 2 switches are both set up but there is no connectivity as I cant ping between them or anything. The management VLAN on the 2960 shows line up, protocol down, which I believe means the VLAN is enabled but there is a form of physical mismtach on the ports. I have attached the configs of both switches. I feel it might be a problem with GBIC module compatibility. The SFP installed on both ends of the switch are GLC-SX-MMD. On the 4510, the SFP sits in a twingig converter (CVR-X2-SFP) but there is no light on it at all when the cables are plugged in.

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.
