Apr 4, 2011we have a cat6509 with FWSM. We pass to the FWSM several VLANs. AllL3 is assigned to the FWs.In the Cat6500 log we have received this message %SVCLC-5-FWTRUNK: Firewalled VLANs configured on trunks ,when we configure 2 vlans in a trunk to an ESX server (these 2 VLANs are alreadyassigned to the FWSM).Idea is to share an interface to a ESX server with several VLANs, some of them are assigned also to FWSM.

May 23, 2012I has a issue about etherchannel beetwen 02 Catalyst 6500 switch, i need your comment about it. if you had any similar experience:

and i see output "show interface Po4A" up up on switch-1, "show interface Po4B" up up on switch-2
5.- In the show running-config not appear configured Po4A and Po4B. it only show on outputs
6.- Po4A and Po4 was not configured on neither switches, my question is why appear Po4A and Po4B on switch-1 and switch-2 respectively? and why Po4 appear in down down.
7.- I solved this issue by shutdown and not shutdown to the interfaces on both routers, currently all is OK.

Sep 13, 2012I have a above said switch at my remote office (600KM) which is connected with L2 Point to Point leased line. Both the ends I have Cisco 3950 catalyst switches with Vlans configured at both the ends. Now, for obvious reasons I should remove the other end 3950 switch and replace with Cisco 2950 switch. The other end 3950 is having 4 Vlans configured on 4 ports. Now my requirement is, I should configure 3 Vlans (one for P2P, one for 10 Desktops and one for to bring traffic from other network).
View 1 Replies View RelatedCisco Switching/Routing :: Catalyst 2970 Switch For 2 Vlans
Oct 14, 2012I am using a catalyst 2970 switch for 2 vlans. Corporate data and a separate VLAN for backups. What I want to do is create an LACP etherchannel to the switch and also trunk these ports so the server is part of both VLANS.Due to fact that some of these servers are on totally separated networks, they really shouldn't be able to talk to the backup server. Creating the VLAN for backups works to achieve this. I plan to create inbound ACLs on each port to allow only the ports and IPs for the backup network and allow everything we need for corporate data.I read somewhere that you can't have ACLs on an etherchannel and I just want to get it all straightened out. I notice I can't add an access group to the port-channel itself but I can on the port- channel member ports. Is this all I need to do or does this not work?

Cisco Switching/Routing :: Created Load Balancing Between Two Catalyst 3550 On Couple Of Vlans
Feb 24, 2012I am testing on lab equipment (2 Catalyst 3550 and 1 Catalyst 3560) HSRP version 1 and 2.I successfully created a load balancing between the two Catalyst 3550 on a couple of vlans (11 and 12) on ver 1
now, just adding the command "standby xx version 2" my hosts on the 2 vlans are completely unable to ping the virtual IP def. gw on debugging i checked that msgs are exchangedthe two cat 3550 are seeing each other on HSRP (active / standby roles)the real ip addresses are pingable rebooted the swiches (just as a last resort try)deleted arp chache on hostsremoved the auth on hsrp all of this no effect.
i also tried to modify the priority on the cat 3560 (before he was on both vlans in standby) to make it the active one and with the same config it worked flawlessly.
My only idea is that there is a bug on CATs 3550 (IOS: c3550-ipservicesk9-mz.122-55.SE4.bin) [code]
Cisco Switching/Routing :: Multiples VLANs On 3750
Jan 24, 2012I have a stacked Cisco Catalyst 3750 configuration that currently has one V LAN configured. VLAN 192 - 10.192.0.0/16
The Catalyst has an ip on this range of 10.192.0.1. I would like to configured a few more V LAN's to be able to run some more network ranges through this device. Would it be a case of just adding the V LAN's to the master and then configuring an IP for each V LAN within the inter-v lan routing section? Some V LAN's will require access to each other but not all.
Cisco Firewall :: VLANs ACLs In A 3750 Switch Stack
Jan 15, 2013A CISCO 3750-X stack with several VLANs and many ACLs applied to the virtual interfaces. Intervlan routing is on. Connected to this stack are VMware hosts and with about 500 VMs.We started using the ACLs to allow connectivity between VLANs to specific hosts and it has grown to thousands of lines. I personally do not think this is good for the switch and believe the switch was not intended to be used for that security feature.
- Does it make it sense to add an "internal firewall" between the CORE ROUTER AND THE 3750-X SWITCH STACK ?
- Do you recommend any other way?
- Any recommended CISCO resource/white paper to read about best practice
Cisco Infrastructure :: ASA 3750 Firewall To Control Traffic Between VLANs
Jan 20, 2013We have a data center with servers set up for different projects, some servers from partner companies and several small LANs. The traffic between all those needs to be controlled and firewalled. The servers and LANs are divided into different subnets and VLANs. Physically, their traffic is aggregated on a couple of 4506 and then sent to a FreeBSD server, where the logical gateways are set up and traffic is filtered between them.The BSD server is dying and having it there is incorrect in the first place, so we are planning to replace it with two ASA (5520) in failover.The question that arises is how to correctly implement firewalling between VLANs. Originally we thought to set up the firewalls in transparent mode and logically terminate VLANs on a stack of 3750 switches behind them, but would that filter the traffic between the VLANs? Then we thought to perhaps terminate the VLANs on the ASAs, use routing mode, and do filtering there, as well. Or should we implement multiple contexts? We have about 20 VLANs and all of them differ in rules of what should go there. None of this can be concidered an "inside" - trusted - zone, nor "outside". Internet and external links are connected and filtered in a different place.
View 1 Replies View RelatedCisco WAN :: 3750 Performing QOS Against Number Of SVI VLans On Per Customer Basis
Apr 29, 2012I have a Cisco 3750 switch stack and am performing QOS against a number of SVI vlans on per customer basis. I have 8 customers, each with a /29 public subnet and each with an SVI as a gateway within that /29 range. I then have a "routable" SVI vlan for routing upstream to the internet. [code]
The service policy attached to the interfaces above is supposed to perform policing on download and upload traffic. The service policy is attached to the Routable VLAN for download policing and the Customer VLAN for upload policing. For example, traffic entering the routable VLAN will be policed based on traffic matching an access list to the customers IP range (download). Traffic entering the customer VLAN will be policed based on traffic matching an access list from the customers IP range (upload).The command I am using to police is as follows - police 10485500 966080 exceed-action drop.The problem I am experiencing is traffic into the routable VLAN is being successfully policed down to the 10Mbps i have specified on a per customer basis (download).Traffic entering the customer VLAN is NOT being policed at all (upload).I am limited as to the use of the parent policy map I have specified on the interface, as I can only assign it in one direction (input).
Cisco Switching/Routing :: 3750 - Transparent Firewall Between VLANs
Jun 19, 2012I have to put an ACL Firewall in front of a public IP range.There's no routing so I want to do it with a transparent layer 2 Firewall. I found this document which descibes exactly that feature I need: [URL]
It seems to be a feature introduced in IOS 12.3.
My Questions:
1.) is it possible use this transparent firewall feature with the 3750 Switch instead of a "normal" IOS-Based router?
2.) I've seen there is no IOS 12.3 for the 3750 but rather 12.2 (currently installed) or 15.0.1. Is this Feature included in 15.0.1?
If the feature described above is not available, is there any other way to achieve my goal?

But along with that I am seeing another AP as rogue on wire, even though i have plugged in only one Autonomous AP to the switch.

Cisco Switching/Routing :: 3750 - Configuring Multiple VLANs For Single Port
Apr 11, 2012I would like to configure a 3750 switch port to be able to use two vlans. I know you can do this with a voice and data vlan, but what about two data vlans ? Say I have two devices, one on a 10 subnet and the other on a 172 subnet, but i only have one wall jack for both devices to plug into. So I use a mini switch to connect both devices and connect the switch to the wall jack; and of course this all leads back to one switch port. When I go to enter the switchport access vlan 172 cmd, how would I also make it so the device on the 10 subnet could route out ?
