Cisco Switching/Routing :: HTTP Redirect Using 3750 Switch

Sep 16, 2012

I have tried search but found found anything for the 3750 switch about how to redirect HTTP, HTTPS & SMTP traffic to altenative gateway, than our standard gateway on our network, so here goes:
 
The network that need the HTTP, HTTPS and SMTP traffic redirect is 192.168.5.0/24 and should be redirect to 192.168.5.205 where as all other traffic need to be direct to 192.168.5.199.
 
Can the 3750 switch do this typo of refirect and if how?? I cannot find anything on the Cisco site stating how or even if it is possible!

Cisco WAN :: WCCP HTTP Access Timeouts With 3750

Jan 29, 2012

I have a web cache server, and I redirect all the HTTP request to it using WCCP.
 
Everything works without a problem, however I have a monitoring system that every minute tests the access to some customer sites that are hosted inside our infra-strutcture.
 
As soon as I configured the WCCP the monitoring system complains of timeouts accessing those sites, about 20% of the requests start to fail (timeout).
 
I don't think it is the fault of the cache because in the WCCP ACL I exclude all traffic that comes from my monitoring system. However as soon as I turn of WCCP the monitoring system never ever gives timeouts accessing those sites.
 
Is there anything I should do in WCCP to tweak it? I have WCCP configured in my core gateway that is a CISCO 3750.

Cisco Switching/Routing :: 3750 To Squid Routing Not Working

Nov 23, 2011

I am using a cisco 3750 in my network as a gateway, and above it I use a  squid machine for caching my internet. My network is like this:
 
Basically I have two VLANs on my network which are VLAN10 and VLAN100,  VLAN10 is the cooperate network of my office. VLAN100 is the management  VLAN which i use for the switches. I keep the squid as well the client  in VLAN10.
 
squid (192.168.1.50)---->cisco 3750(192.168.1.123)---->Distribution Switch(cisco 2960)---->client PC (192.168.1.5)
 
I have done nating on squid and internet is working pretty fine when I  use the client gateway as the squid, but when I use the cisco 3750 as my  gateway after adding route maps for forwarding the internet traffic  coming to the cisco 3750 to squid it disconnects me from internet as  well I cannot even reach the switches from the corporate network. These  are the only Lines I used for the routing:
 
!
route-map proxy-redirect permit 10
match ip address 110

Cisco Switching/Routing :: 3750 / PBR Routing Not Working?

Jan 3, 2012

My network is like this:
 
Cisco 3750 (Core Switch)-----> Cisco 2960 (Distribution Switch)----->  Client (PC, Laps, Printers…etc)
 
Basically I have 3 VLAN’s. Office VLAN (for cooperative usage) which is VLAN 999 which has a defined IP address of 192.168.1.123 and Guest VLAN (for the guests who visits our hotel, most of it are wifi AP’s) VLAN 20 which has an IP address of 10.172.4.1. All these SVI are defined on the core switch.
 
Is there any way I can introduce a new VLAN lets say VLAN 40 and use PBR to route the packets going to VLAN 40 in the IP range 192.168.1.x to VLAN 999 and 10.172.4.1 to VLAN 20? I have tried this already and it is not working. Here are the configurations I have used.
 
Access-list 110 permit ip 10.172.4.0 0.0.0.255 any
access-list 120 permit ip 192.168.1.0 0.0.0.255 any
route-map INT_RVLAN permit 10
match ip address 120 110
set ip next-hop 192.168.1.123 10.172.4.1
interface VLAN 40
ip policy route-map INT_RVLAN
 
Where have I gone wrong?

Cisco Switching/Routing :: 3750 - Gigabit Ports Not Working

May 1, 2013

I have two switches, WS-3750-24PS-S connected in two cabs via fiber. Patch panels at both ends with patch leads. Used tester to confirm end to end fiber connectivity. When plugged in, one switch lights up the other does nothing.
 
Ports are as follows:
 
interface GigabitEthernet1/0/2
switchport trunk encapsulation dot1q
switchport mode trunk
 
same at both ends. Tried both GI ports same result. swapped transceivers over and the same result, (one switch lit one not - the same switch in both cases). put both transceiver in each switch, (gi0/1-0/2 in a single switch). on the one that lights up in the original scenario we get link on both ports and they come up, on the other nothing happens. shut down both ports on the malfunctioning switch and no shut them, no change.
 
Show transceivers doesn't show transceivers on the malfunctioning switch, and no attempt is made to bring the ports up if the fiber is removed and replaced.
 
it is almost as though the two gb ports are kaput. Anything else I can try?

Cisco Switching/Routing :: 3750 - New Switch Not Working Correctly

Jan 30, 2012

I have a Catalyst 3750 switch configured in a network. I would like an additional 3750 switch as a "hot" standby. A 2nd 3750 switch was purchased, and the same configuration was entered in to the new switch, so I have 2 switches with the exact same configuration.
 
When I move the connections to the new switch, I have a few VLANs that do not come up. One VLAN does come up and work normally. The VLANs in question show down, protocol down, and a show ip route reveals routes to the networks on these VLANs are not there When I put everything back on the original switch, everything works normally.
 
Why would the new switch not work with the exact same configuration?

Cisco Switching/Routing :: 3750 / Access A Target Server With IP Address 10.2.2.13?

Oct 16, 2012

Today when we run one applcation to access a target server with IP address 10.2.2.13, the application cannot run through and appearing error message related networking.The target server has two network ports whereby another one with IP 10.2.2.14 is running OK with the same application. All these two connections are connected to the same Cisco switch 3750, after the switch then go to Cisco ASA firewall which has no access control rule for this 10.2.2.13 and its subnet, and then the firewall connect directly to the application server.We can ping, remote desktop access and telent port for the application to the target server by using 10.2.2.13.We swapped the cable connection of the ports from one another and try the application again, the IP with 10.2.2.13 is still fail and IP with 10.2.2.14 is OK.We then change the IP from 10.2.2.13 to 10.2.2.12 or 10.2.2.155, all are OK. We changed back to 10.2.2.13, it is failed again.The switch is in running real time production and so we cannot power cycle or reload the switch.

Cisco Switching/Routing :: 3750 - Internet Access Through MPLS Cloud

Sep 11, 2012

I need to confirm internet access from remote network through MPLS cloud to another site. Let me explain. We have a MPLS network with Wind stream as listed in the visio drawing; site 1 has internet access through the Time-Warner cloud for all users. Site2 has internet access through the Wind stream MPLS router. Site three has no internet access, and only has LAN access layer2 through Windstream routers to Site1 for networks 192.168.0.0/24, 10.1.1.x/24. My question is can we give everyone at Site 3 internet access through the MPLS network down into Site 1 using the Time-Warner ISP cloud.
 
I placed routes on the Site 3 3750 stack IP route 192.168.50.x 255.255.255.0 to the interface of the MPLS router at site3, then at site 1 we have IP route 192.168.50.x 255.255.255.0 to the MPLS interface, and able to ping all anything on the 192.168.50.0 network. I added the IP route 0.0.0.0 0.0.0.0 192.168.50.x the MPLS router interface, we do not have internet access at Site 3 using Site 1 network.
 
I confirmed at Site 1 from the Cisco 3750 switch we can ping 4.2.2.2 = Google. How to confirm this will work and what’s required to complete this connection to give everyone at site 3 internet access through Site 1 Time-Warner.

Cisco Switching/Routing :: 3750-X OOB Management With IP Base And Routed Access Layer

Aug 14, 2012

I've got a bunch of 3750-X switches all running IP Base and acting as a routed access layer. They run OSPF in a totally stubby area with the distribution layer (Nexus 7K) as the ABR. We also have a physically separate management network into which the fa0 management interface of the 3750-X is connected. The management network itself runs OSPF and has multiple subnets and external access.
 
On the 3750-X, I'd ideally like to be able to run some sort of separate OSPF process for the management network or at the very least have a static default route for management traffic pointing out the fa0 interface, but clearly not have it interfere with the main default route for data traffic coming from the N7K ABR. Normally I'd just create a management VRF, sling the fa0 interface into it and run a separate OSPF process in that VRF. The problem is you can't create VRFs in IP Base! Surely there must be a way to do this? Cisco don't really expect customers to upgrade to IP Services just to have a working OOB Management network, do they?!

Cisco Switching/Routing :: 3750 - Rapid Spanning Tree In Access Layer?

Apr 9, 2012

My colleague and I have been having a discussion about using rapid spanning tree in the access layer.  Most of our infrastructure has been migrated to a routed access layer with 3750s.
 
The idea was brought up to configure the switches with rapid PVST.  On the surface, it seems like a better idea, faster convergence, in the event that spanning tree ends up being used for some reason.  My colleague prefers sticking with standard PVST.  His argument is that, in the event of a layer 2 loop, some consumer-level switches filter out BPDUs and if the control plane is overwhelmed, the shorter timers of rapid PVST just puts that much more of a burden on the CPU trying to regain control, whereas with standard PVST it will have around 20 seconds before it starts to engage.  (It may still be overwhelmed, but the longer timer delays the additional burden.)  He says he's seen this problem with rapid PVST and that his opinion is backed up by our Cisco rep.  (I haven't spoken to him yet.)
 
In our model, it should be very rare -- pretty much never -- that we would layer 2 span another switch off of our access stack.
 
One suggestion I saw is to use BPDU Guard, which is a good suggestion as well.
 
But we have had experiences with overloading the control plane on a 3750.  I believe that concern is valid.  If the CPU can't service spanning tree. But I'm interested in hearing about other experiences people have had in terms of rapid spanning tree in the access layer, end users plugging in unauthorized devices and creating loops, and the effects when using rapid spanning tree vs standard spanning tree.
