View 2 Replies View RelatedCisco Switching/Routing :: 3825 / Replacing Routing Function With 3750 Switch?
Jul 27, 2012I have the task of replicating the router config on a 3825 router on a 3750 switch. Reason is we are taking out the router and replacing it with the switch to make use of the router for other functions.
Below is main part of the router config:
!
ip source-route
ip cef
!
!
multilink bundle-name authenticated
!
license udi pid CISCO3825 sn FCZxxxxxxx
!
vlan internal allocation policy ascending
[code].....
The 3750 switch I have runs C3750E-UNIVERSALK9-M, Version 12.2(55)SE3 on a LAN BASE license.
The first thing I have done is to order for a license upgrade to IP BASE which would give the support for OSPF routing.I do not see much of an issue with the Interface configs, however, I am not too sure about replicating the routing config on the switch.
My question is can I run the commands as shown for the OSPF routing on the switch? If not, can I get suggestions on how best to set this up on the switch?
Cisco Switching/Routing :: 3825 Wacky Routing With VLAN
Apr 9, 2012I have a 3825 router that I have setup with the following: [code]
Its on a trunked port to my 3750 switch. I am new to this compnay and havent changed it over to IP routing on the switch quite yet.Both Vlans are setup on the 3750 without an SVI. All hosts on VLAN 1 can ping both interfaces without issue.
If I put a host on the 172 VLAN it cannot ping anything on the router. If I put another host on the VLAN they can ping each other. If I put an SVI on switch the 172 VLAN hosts can ping the switch, but still not the router. ONce I put the SVI on the switch, it can no longer ping the router. I am giving the SVI ip 172.22.1.5/24.
I have verfied with TAC that the trunk is allowing the vlans to the router.
I have been working with TAC. They have asked me to update the code on the switch, but I think they are just punting. [code]

Cisco Switching/Routing :: 3825 - GLBP Is Not Working
Feb 22, 2010I have 2*3825 routers configured with GLBP, but traffic is moving only with one router it only fallback on other router when the 1st router is isolated.
diagram: LAN=======>ASA(Routed mode with active-standby)======>one Cisco L2 switch========>2 *3825 Router
When trace route from LAN PC show that traffic is only taking via single router. LAN gateway is defined as ASA inside address and in ASA a default route pointed to GLBP address.
RTR1 config:
==========
int g0/0
ip address 1.1.1.2 255.255.255.0
glbp 1 ip 1.1.1.1
glbp 1 preemt
RTR2 config:
==========
int g0/0
ip address 1.1.1.3 255.255.255.0
glbp 1 ip 1.1.1.1
glbp 1 preemt
Is there any other config is required?

Cisco Switching/Routing :: 2960 / SG 300 Switch - VoIP Setup - Asymmetric Routing Not Working
May 21, 2013I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.
Cisco Switching/Routing :: Can Port Channel In 3825 Connect To Two Different Switches
Jan 17, 2012We have one 3825 router used as voice gateway. For redudancy, we want to connect it to two different switches which has STP and HSRP running. Can I create a port-channel with two Giga interfaces in 3825 and connect to two different switches? Should I configure port channel in switch with only one port in each port-channel? I know server can be connected to different switches with NIC teaming. I just want to mimic that kind of setup. I did one time for port-channel in 3825, but it was connected to a stacked 3750X. So it's different case now.

How should I treat uplinks between access switchs and core/distribution? I have a lot of doubts regarding queueing, because all the info I had read its for another model/image.
View 4 Replies View RelatedCisco Switching/Routing :: 3825 How To Configure A Broadband Backup For MPLS Circuit
Apr 16, 2013I 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.

View 1 Replies View RelatedCisco Switching/Routing :: QoS On 3750x For VOIP Implementation?
May 23, 2013We are going to be expanding our Shoretel phone system in our HQ and I need to get QoS configured correctly. All of our offices are connected via MPLS and I need to make sure that we are sending QoS tagged traffic to our provider. The phones are tagged by the director, but there is other traffic for call control that needs to be tagged. I don't have access to our CPE router as it is managed by Sprint. The Sprint router is connected to our internal network. We have our data network running on (4) 3750x switches running 12.2(55) with IP feature set.
The problem is that many of these commands don't work on the 3750 (priority, bandwidth, match protocol, etc...) and the configuration assumes you are applying this to an outbound queue which is not supported on the 3750. I think I have to do this with policing, but I'm not sure what interfaces need to have this applied.

Cisco Switching/Routing :: 3825 - Use HSRP Or VRRP If Not Two Valid / Unique Wan IPs To Assign Routers
Apr 24, 2008Our ISP hands us an ethernet link. ISP router has one address of (for argument sake) 1.1.1.0/30 net, - let's say they have 1.1.1.1 we have the other usable address of 1.1.1.2/30 assigned to our 3825 router. Is it possible to use hsrp or vrrp if there is not two valid/unique "wan" IPs to assign to our routers? For example, if we had a pair of 3825 routers? are we stuck with basically a manual failover or requesting our isp to provide a larger address wan block?

Cisco Switching/Routing :: QOS For VOIP Traffic On Nexus 7000
Mar 4, 2012regarding QOS on Nexus 7000. Our Nexus 7000's form a collapsed distribution/core layer, our access layer switches are are a mixture of Cisco 3750 & Cisco 4507. 3750 switches will connect to Nexus switches via 1Gb uplink, 4507 switches will connect via 10Gb uplinks. Each Nexus will be connected via 20Gb port channel, all servers connect to the Nexus switches via 1Gb links. We're implementing a new telephone system soon which will be using VOIP so I need to configure the switches to perform QOS. The IP phones will mark the RTP traffic with DSCP value EF and call signaling traffic CS3. I'm fine configuring qos on the access layer switches, its just the Nexus switches which I'm not sure about.
Do I actually need to configure any QOS parameters on the Nexus switches so they will prioritise the VOIP traffic. If my understanding the Nexus switches will trust the DSCP values and assign the traffic to the relevent queues?
Just for information VOIP is the only traffic I will be marking QOS values

Cisco Switching/Routing :: Difference Between Auto Qos And Voip Trust With C2960S
