Cisco WAN :: Set Up QoS Between 2811 Router And 3750g Switch?

Feb 14, 2011

I'm trying to set up QoS between a 2811 router and a 3750g switch.  I'm currently using the 3750 as the router for one side, having the interface connecting to the router as a routed interface. 
  
I have this config on the router side:
  
 class-map match-any IPTel-Traffic-CL

Cisco Security :: To Put A Switch 3750 In Place Of 2811 Router

Dec 29, 2011

I have an ASA 5510 that I want to connect to 2 isp (one of my private network uses the isp1, and all others the isp2). Excluding the 5510 does not accept PBR(policy based routing), i saw that you could put a router, like cisco 2811 in front of the ISP. my questions are : can i put a switch 3750 in place of the 2811 router? , I have vpn connections in isp1, this architecture is compatible?

From the command

It's normal?If not, then. the problem is on the cable or on one of the interfaces?The interface is connected between a fastethenert on a 2811 router and a 3560-48 switch.The cable is a straight through cat 5e cable. (I have changed several cables with same result).

Cisco Switching/Routing :: 3750G Spanning Tree On New Switch Stack

Nov 3, 2011

I am about rip and replace my current 3750G stack with a 3750X stack. I have trunked over vlan and vtp info and implemented a config so it should be ready to go other then moving cables onto it. However one thing I want to correct with our current setup is that the root bridge on our vlans including vlan 1 is on a separate set of switches that we control, however I would like this new stack to be the root bridge for all of our vlans. It will be the central set of switches that all other switches trunk into.  I have pre-set higher spanning-tree priorities for each vlan on the new stack so I expect as I move lines into it that the tree will be re-calculated with it as the root bridge. I've ensured that there are no root guards on any of the other switches trunks and priorities are all at default levels for each vlan. Should I enforce root guard on the trunk interfaces of the new master stack?  Most of the trunks are port-channels to the other switches - do I need to set root guard on the Port channel interface or on the individual ports that make up the Port channel? On both? Any other recommendations in regards to implementing spanning-tree with the new stack? I know using port channels eliminates a lot of potential for loops but not every trunk is and I'd still like to have spanning-tree on.

Cisco Switching/Routing :: 3750G - Adding Additional Switch And Making It Stack

Feb 29, 2012

I currently have Cisco 3750G which is currently live and active and fully populated and only have remote access.
 
I have an additional same switch which I would like to stack. My initial plans were to have 2 GIbit etherchannels, but I came across the option to Stacks both switch with each other.
 
When I do a show switch on the live switch its set as a Member: [code]

I would like to add the new switch to the stack without losing the config for the switch which is live. I understand that the highest priority of the switches becomes the Master but as the live switch is Priority 1, would chancing this affect the switches config, or would it lose connection at all?
 
Also when I plug in the new switch and it reboot how do I ensure it becomes the slave without rebooting the live switch?The cables on the switch do they have to go to port1 on the live switch and port 1 on the new switch or can they be port 1 and port 2?

Cisco WAN :: 2811 - Routing The Switch Ports

Mar 10, 2011

I have a 2811 router with a 9 port switch module and a four port ISDN module.  The ISDN Module is our connection to the outside world.  FE 0/0 and FE 0/1 are connected to separate networks and both route our the ISDN connections.We are getting a new satcom system that consists of a modem, antenna control unit (ACU), and an antenna.  The ACU and the modem communicate accross Ethernet and are generally hooked to a switch.  Anything computer hooked to the switch can simply use the modem IP as it's gateway and be surfing the Internet without much hassle (just need the correct DNS addresses).I'd like the networks behind FE 0/0 and FE 0/1 to be able to route out the satellite modem for their Internet connection -- when the satellite is available.  Is it possible to put two switch ports in a VLAN (one for the modem and one for the ACU), give the VLAN an IP in the same subnet as the modem and ACU, and then tell the router to route traffic out the modem IP address ?

Cisco WAN :: 2811 HWIC Switch Cannot Be Configured As A Network Interface

Apr 14, 2012

I currently have a Cisco 2621 powering a network at our  co-location facility... It's a simple setup and is working well. The colo  provides a redundant HSRP uplink, so I have their two uplinks going into  a Dell switch. From that Dell switch I have a uplink into  FastEthernet0/0 on the 2621, configured with my routing network, and  then FastEthernet0/1 gets an address from my block of routable IP. FastEthernet0/1 then plugs into another  Dell switch where I have all my servers connected. The servers get public routable IP addresses and use the address on FastEthernet0/1 as their default gateway.
 
It's time to upgrade off the 2621, so I aquired a Cisco 2811 which has two FE interfaces, as well as a modular HWIC-4ESW switch. My question is, can I get rid of the Dell Switch A in the setup above and just use the internal switch on the 2811 to accomplish the same thing? And I if I did this, would my two uplinks from the colo plug into ports 1 and 2 of that HWIC, and then port 3 would physically connect into FE 0/0? Or can I logically do that via configuration in the Cisco? I'm not sure how all this works and haven't received the new router yet, so I thought I'd get a head start and reach out to the experts.
 
My second question is unrelated, but each port on the HWIC switch cannot be configured as a network interface right? I'm pretty sure they can't as they aren't considered network interfaces but just thought I'd ask.

Cisco Switching/Routing :: 2811 With 16 Port Switch Module Configuration?

May 12, 2013

I have a laptop with a single physical NIC which I have used the advanced management tools to create two virtual NICs (say vlan 10 and vlan 20) and both are on the same subnet (say 192.168.4.x). One NIC is for normal TCP/IP traffic and one is for broadcast/multicast traffic (I have some custom software that requires this to be the case and works fine on an older laptops with built-in physical NIC and PCMCIA XIRCOM NIC). The dual NIC laptop communicates with a dual NIC server via a Cisco 2811 router (which has a 16 port switch module at the back) and has vlans set up so.
 
What I want is for the single NIC laptop (with two virtual NICs) to be able to also communicate with the server. Basically, one NIC is for normal traffic and one is for multicast/broadcast traffic. All three machines need to be able to talk to each other using the NIC for normal traffic and both laptops must be able to receive broadcasts from the server. What is the best way to configure the router to handle the trunking/tagging? Most configuration documentation I read has two complete subnets for the two virtual NICs. Note that all three machines use static IPs and are part of a workgroup so no DNS and domain servers etc.

I call to ISP they ask me to config extactly VLAN id 10 in the physical subinterface. But in subinterface there is no command "pppoe-client dial-pool-number". I check the old modem FTTH, they also config VLAN 10 in Wan interface. I tell ISP why we have the same two FTTHs, but two differrent config ways. ISP says because the two line run in two different infrastructure, two different devices. I don't know how to do now? stay in customer side or ISP side. Here is my PPPoE config:
 
interface FastEthernet0/0
no ip address
