The Issue we have two 3750 switches and configured hsrp on that . Now instead of connecting these two swiches to an Intermediate common switch we have a cisco asa5520 which has 3 L3 ports of which is it possble to convert 2 ports as L2 ports and use those ports to connect to 3750 switches instead of a L2 switch.

View 5 Replies View Relatedi have a 6509 connected via layer 2 (VLAN1) to a 3750 (e.g. VLAN1 10.1.1.1)then to the HQ via Metroethernet(L3). Is it possible to connect the 6509 to an ASA that already has VPN connectivity to the HQ using HSRP? Also need to mention, the VPN connection is supposed to be the redundant connection if Metroethernet link fails.
View 3 Replies View RelatedI am facing a problem in implementing HSRP. My scenario is like this, I have two 3750 switches and I have a server with two NICs. I want to run HSRP in these two switches. By the way the server is connected directly with the switches. I mean each NIC to each switch.we have teamed the two NIC (Active / Standby).what configuration need to done in switches to work HSRP.
View 4 Replies View RelatedI'm trying to configure load balancing on a network that is using 4 3750 L3 switches. The network is comprised of two sites with two switches at each site running HSRP and the virtaul IP is the gateway for a server between the two switches. The sites are connected by two independant 200meg ethernet connections (technically they are GigE limited to 200meg) p2p circuits. The switches at site A are connected together via a GigE port and the server I have connects to each switch at its respective site using a GigE port and the same for site B.
The problem I'm running into is that I've noticed that one of the 200meg circuits is always idol unless the primary goes down, so I'd like to be able to load balance the traffic from site A to site B using both p2p circuits. I think the problem that I'm running into has to do with the fact that HSRP is putting one of the links from the server to switch in standby unless the WAN link goes down and therefore traffic is not taking the "longer route" to the 2nd 200meg circuit.The only traffic going across this network is only the two servers sending traffic to one another. how I can get load balancing to work or if it is a possiblity with this network topology?
I have a 3750 stack and want to confirm if I can run HSRP on the stack to two different ASR routers for redundancy purposes ?

What should the duplex mode to be set on a routed port gi0/21 that are running HSRP ? I try setting the gi0/21 to full, but it caused the port to be down. The only way for the port to be up is setting it to half duplex.

I understand on older IOS codes If the same hsrp group number is assigned to multiple standby groups, it creates a non-unique MAC address. Is this true on newer codes like 12.2(52)SE for 3750 & 3560?

We have our WAN setup as explained in the attachment herewith. As of now, We have a IP 1 configured as HSRP IP in the LAN switch end at Site A and Site B. As per the HSRP priority, Site A's WAN router will preempt to be the Active WAN router. 1*1Gig link at both DCs connect to the respectve WAN router.
But with this setup, we experience a WAN outage whenever there is a link disconect at Site A - as HSRP fails over from Active to Standby(Site B) and again when the link at Site gets restored. To avoid this :
Is it possible to have the HSRP configured over a port channel at Site A and B (or atleast at Site A) ? In that case, will there be a need for the ISP to change their configuration except to configure a port channel ? The ISP has Cisco 7000 series router which connects to 3750 stack at DC lan.
We have 2 access switches (3750s) that are both attached to a pair of Nexus 5548UPs with L3 cards over VPCs. Access switch (AC1) terminates our 4402 WLC. The WLC services 4 WLANs and connects to the access switch with a single trunked port. Access switch 2 (AC2) terminates an 1131AG lightweight AP. The WLAN is 10.1.1.0/24 on VLAN 300. Router 1 (R1) VLAN 300 IP is 10.1.1.2. Router 2 (R2) VLAN 300 IP is 10.1.1.3. R1 is the active router for VLAN 300. The standby IP for VLAN 300 is 10.1.1.1. The VPCs between both access switches and the router pair are functioning correctly and trunks are wide open (no pruning).
Wireless clients get a DHCP address from a server on another VLAN. Those addresses get handed out just fine.
Wireless clients can ping 10.1.1.3 (R2). They cannot ping 10.1.1.1 (standby address) or 10.1.1.2 (R1).
I took captures from the WLC and I see the ARP requests and replies from wireless clients to their gateway (10.1.1.1). I took another capture directly from the wireless clients themselves. From there, we see the ARP requests, but never the replies. If I create a static ARP entry on the client, it can ping the gateway just fine.

View 2 Replies View RelatedI have a question in regards to configuration I'm planning to implement. I currently have 2 x 3750 running in a stack. I would like to add 1 x 870 router connected to both switches.It's important for me that 870 is always available (it will only be used as a backdoor for our management network through WAN) but I don't want it to participate in any switching (including switching for management network unless it's going through this backdoor WAN). Do I need to configure spanning tree on all switches or stack is automaticly working as a 1 logical unit?As router is only using 100MB/s connection, how I can prevent this router from switching packets with other switches?

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)
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?
I´m looking for the best configuration to restrict a user to read-only. The restriction should be configured via CLI not TACACS+.
-Hardware: 3750 (probably not interesting for this question)
-Oldest IOS: 12.2(53)SE1
The user should be allowed to: see the running-configurationtrigger all kinds of show-commandsping and traceroute from the device.The user should not be allowed to: upload/delete/rename files on the flash-memoryget into level 15 (not sure if I can avoid this)all other commands despite those from level 1 and those specified above.
I'm looking to configure a syslog server for all of my cisco device logging. I've had a look at CNA and can't find any options to define a syslog server for my switches.
What's the best way to define a syslog server and the severity of the notifications? Also, i'm looking to clear all previous Syste mmessages fon my devices?
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
[code]....
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.
