Cisco Switching/Routing :: 5510 How To Configure A Backup Route To Internet

Jul 24, 2012

how to configure a backup route to the internet.  My client has 2 ISP and basically they want to use 1 ISP and in case the ISP fails, use the other one as backup route to the internet.
The problem I’m facing is that each ISP is plugged to a dedicated ASA 5510, so 1 ISP in one firewall and 1 in the other.  Both ASA are plugged to an internal network in a dedicated VLAN with a L3 switch and that L3 switch manages the internal network.
My question is, how can I tell my switch to use ASA1 to go out to the internet and in case the ASA 1 OR THE LINK TO INTERNET used by ASA 1 fails, use ASA 2?  It would be great if I can send traffic to the internet thru both connections at the same time.  Also, I know the ASA has High Availability configuration, but that applies only if both licenses in the devices are the same and I have a mismatch with the SVPN license, and also I don't know if with my current topology I can use the High Availability model, so I think I can’t use that option and the solution must be applied in the L3 switch, but I don’t know how to tell it to use ASA1 and if failure of the device or the outside interface plugged to ISP 1, then use ASA2.  Besides, I would like to know how to optimize this config to do the switch between internet connections seamless to the users if possible (there are VoIP calls on this floor, so I don't want to drop the calls).

Cisco Switching/Routing :: 3825 How To Configure A Broadband Backup For MPLS Circuit

Apr 16, 2013

I thought I saw a post/question in regards to "how to" configure a Broadband backup for a MPLS circuit..  What I am trying to do is use a cable/dsl/ broadband (secondary) connection as a backup to a MPLS circuit (primary).  I have EIGRP and BGP configured on both the branch endpoint and the tunnel headend.  The tunnel is used by the interface that connects to the secondary circuit.  The branch location router is a 1841 and the "headend" tunnel router is a 3825.  I am wondering about the configuration/syntax of a "weight" or static route that can be used to have data flow over the tunnel when the MPLS circuit goes down - and then switch back to the MPLS circuit when it comes back on line.

Cisco Switching/Routing :: How To Configure Policy Based Routing On 3750

Jan 28, 2013

In our datacenter we have a 3750 stack with IP base image.  I have enabled PBR and reloaded the switch.  Show sdm prefer says i am using default template.  The reason i want to use PBR is that we have 2 firewalls on the same work and want to be able to have granular control over which gateway out of the network they use but still be able to access all internal resouces accross wan and locally.

Created access list to identify traffic:
access-list 10 permit (test workstation on vlan 3)
Created policy:
route-map TestASA permit 10
match ip address 10
set ip next-hop
Assigned policy to the user vlan3:
ip policy route-map TestASA
Results:It changed the default gateway to the above gateway but i could not access any resources on any other vlan, could not access resouces accross wan.

Cisco Switching/Routing :: Why Is 3750 Switch Have Configuration Register Of 0xF

Apr 17, 2012

I am uploading new configurations to my Cisco 3750 stacked switch and noticed that after the load I cannot log back into the switch because my password somehow was changed. After performing password recovery and getting back into the swtch, I noticed the configuration register was 0xF. I have never seen this before. The config-register command does not seem to be supported to change it back to factory default. The switch is on a ship which has several power hits when they switch power from shore to ship power.Can this cause the configuration register to change? What is the best way to change the configuration register?

Cisco Switching/Routing :: 2960 / 3750 - Best Configuration For This Scenario

Jul 26, 2012

I'm fairly new at trying to create isolated network segments on Cisco switches. What I'm trying to do is have multiple isolated paths that originate from my v Sphere infrastructure travel through a layer 2 link, v LAN, up to a MLS, and ultimately out to to the internet through a firewall. Each sub net might ultimately have a number of hosts on it, but I don't think the make up of those hosts will matter here.
My initial thought was creating v LAN tagged port groups on v Switches on my v Sphere infrastructure. Physical connections will go from my ESXi hosts to the 2900 series Cisco switch connected to trunk ports. Both v LANs would be configured on the switch but not assigned to physical ports. The physical connection to the 3750 would also be a trunk port connection from the 2960. The 3750 would have SVI's created that are attached to VRFs that would control route traffic. This might be totally wrong but from what i've read it seems to be going down the correct path I think.
Two part question, is this the best way to go about designing this network? If so I seem to be really struggling with the SVI/VRF part. Every time I create an SVI all of my hosts on the 10.10.10.x network can ping them, regardless of which v LAN they're on.
I just cannot seem to isolate the 172 network.

Cisco Switching/Routing :: SPAN Port Configuration On 3750?

May 23, 2012

I'm trying to configure a mirror port on a 3750. This configuration needs to replicate data from local ports, but I need that also act as a regular access port.
With the initial configuration, SPAN port, there is no problem, all the data of the configurated ports is replicating in the configurated port. On the port configurated as mirror there is a PC connected for audio recording. When the port is not operating as SPAN there is communications without problem over the LAN. But when I configure the port as SPAN, communication is interrupted.
Here is the actual configuration:
SWITCH1-PISO7#sh monitor session 1
Session 1
Type                   : Local Session

Cisco Switching/Routing :: Configure Inter-vlan On Catalyst 3750

Dec 20, 2012

My architecture is the same as show on the link with some difference.I use the router 1841 for inetrnet connexion instead of 7200VXR, this router 1841 is connected on the catalyst 3750 port G1/0/1.I use catalyst 2960 instead of catalyst 2950 or 2948.I use ASA 5510 for conexion on remote branche(I have 5 remote site), This ASA is connected on the catalyst 3750 port G1/0/37
Result of the test:

-I can ping devices in the same Vlans
-I can ping devices in different VLANs
-I can ping all device from the catalyst 3750
I cannot ping the router 1841 or ASA 5510 from the any devices (computer)The gateway of each computer is the correpondant VLAN IP address configured on the catalyst 3750.Why I cannot ping the router 1841 or ASA 5510 from the any devices (computer)

Cisco Switching/Routing :: 3750 Manage And Configure An External Switch And Router

Apr 3, 2013

1. How I can manage those devices, the Switch and the router? What is the BEST SOLUTION to manage this devices?
2. I want to monitor the traffic on this environment, how I can do it? How I can monitor the traffic from customer A, Customer B, and my own LAN traffic, in terms of bandwidth that has passed throught my devices? Is it possible to monitor on MY LAN, or I have to monitor from the EXTERNAL switch?
3. How I can limit the bandwidth? I was trying to configure it using access list, with policy-map, etc....and limit this on each interface. [code]

The interface does not support the specified policy configuration and/or parameter values.Assigning a policy map to the output side of an interface not supported.With I few reading, I could see that the SWITCH 3750 doesnt support this configs.My INTERNET LINK is 30 Mbps, the ports on the Switch (WS-C3750X-48P-L) are Gigabit Ethernet.How I can limit the bandwidth here? For example, How I can limit a interface to 3Mbps..I was thinking about this:

- Limit the interface to 10Mbps: speed 10

- and limit the interface with 30% of this speed:  srr-queue bandwidth limit 30
Does this work for both UPLOAD and DOWNLOAD?When the packets passes that 3Mbps limitation, will they be droped?

Cisco Switching/Routing :: Configure Port-Channel Or Physical Interface On 3750

Jan 12, 2012

how to configure this. I did it in the past but kind of forgot how I did it.I have a stacked 3750 (two physical switches) connecting to a 2960.
I am creating trunk ports with limited access to VLAN 300, 600, and 700.
There is two interfaces connected from the 3750's(one on each physical stack member) to the 2960.I have the physical interfaces configured exactly the same.
3750 Config:
interface Port-channel2
 interface FastEthernet1/0/46
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1, 300,600,700
switchport mode trunk
speed 100


Should I keep the configuration on the physical ports and not configure the Port-Channel Interfaces? Do I need to configure port-channel load balancing? Is the channel-group mode sufficient? Goal is to basically create 2 links to the 2960 to double the bandwidth and provide redundancy.

Cisco Switching/Routing :: Min-Link Configuration On 3750-X Port-channel

Feb 27, 2013

I am building a new network and intended on using the min-link feature on my port-channels between a 3750-X series switch and Nexus 4k.

However reading further into this it seems this feature is only supported on higher end models. I cannot find any reference to the min-links feature in the 3750-X configuration guide. Is this an available feature?

The 3750-X model is WS-C3750X-24T-L running IOS 12.2(55)SE3 IP Services

My thoughts is that the is only an LACP supported feature so I may not see the command until I have entered an LACP specific command on the port-channel but unfortunately I do not have a 3750X to verify this on at present.
