I have been asked to research running VSS between 2 6509's between 2 sites?
I am just going through the whitepapers and need to establish the link requirements for such a setup.
Is it a valid setup?
I understand that jumbo frames need to be enabled end-to-end. I have two ESX hosts connected at each site. I want to enable jumbo frames for those ports, but what if not all host on the ESX are using jumbo frames, will I have drops and connection failures? So if i have two sites, each with a 6509 connected via a trunk and need to enable jumbo frames for a vlan between the sites how do I accomplish this?If I enable jumbo frames on the trunk link how does that impact other traffic between the sites?

We are implementing the network design between the two sites (OLD Data center and NEW Data Center), scheme in attachement.
We have chosen this scheme on the following criteria:
- A single IP network between the sites (for simplicity migration);
- Fault tolerance via different ISPs.
But the problem is L2 etherchannel doesn't work correctly: When one side port is shutting down, on the other side etherchannel will not rebuild and does not see that link down on the other end. We have tried to use LACP in etherchannel (mode active on ports), but result was the same. Is it on the ISPs side?
Should we use this design or we have to subneting the network and make connections between the data centers classically with L3 channels and OSPF?
The configures of Core ports listed below:
OLD data center core (Cat 6509):
interface GigabitEthernet2/6
description #### TO DATA-CENTER core 1#####
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 5
switchport mode trunk
logging event link-status
when I try to enable a WLAN that is using the same SSID as another WLAN I get this message
The following errors occurred while updating the WLAN:
WLAN with duplicate SSID and L2 security policy found.
each location has its own interface because each site is setup on our 6509 with a different VLAN. What is the best way to work around this.

I have restricted access to users using TCP/IP using cisco 1841 router in my organization.
I need to permit some sites for users which are part of work..
The issue here is I cannot ping to the site but able to browse to that site when having internet access, i have permitted range the entire range of that IP's but still no luck..
url...is the site which is not pinging from internet.I have also checked the source code for the root IP but still no luck.
For a simple 4x sites design for backup consolidation (3x sites connected to one central site), does the design in the attached JPEG make sense and is the configuration achievable using the specified parts?
Brief Explanation:
- Each site is to have servers with 2x 10Gb/s Ethernet (both teamed/bonded/etc) and one NIC on each of the 2x switches in the site (if possible). Each site will also have 2x Cisco Nexus 5596UP Switch (though the P version may be used instead of the UP).
- Two of the sites are within 10KM of the central site
- The last site is about 35KM from the central site
- It is required to have a minimum bandwidth of 10Gb/s between any site and the central site
- I have specified 10Gb/s LW SFP+ and 10Gb/s LW SFP+ (for the 2x 10KM and 1x 35KM sites)
- are there any special licenses needed?
- as asked before, can such a "simple" design work as-is?
- what sort of single-mode fiber would fit the bill (especially for the 40KM link) - 9nm?
We are having two sites seperated by half a mile and we are using dedicated 100 Meg link at the moment for intranet traffic, and now we got new 1 gig link and I am working to set it up, Service Provider came on site installed two circuits on both sites and fiber connectivity is tested succesfully betweeen sites, now I need to connect the circuits to our network and make the 1 gig link active to make traffic flow between sites and as well bring 100 meg as standby.
So to brief the issue:
Connectivity at the moment SiteA: Switch1(3560)------100Meg--------.SiteB: Switch 2(3560)
I Want to configure SiteA: Switch 3(4507)------1gig (Active)--------.SiteB: Switch 4(3560) SiteA: Switch1(3560)------100Meg(Standby)--------.SiteB: Switch 2(3560)
simple as connecting a fiber or ethernet link from external circuit on both sites to respective switches on their interfaces and configuring hsrp to enable redundancy. A
We currently have a main network running through a static broadband connecting using a Cisco 1700 ADSL router, everything is working fine locally.
We are looking to rent some space in an office nearby so im going to order another business adsl connection with static IP for this site and i currently have a spare 1800 router.My question is can the cisco routers connect up like a VPN connection so both sites work together and will the connection remain online constantly so from the remote office we can access all our servers from the main network?
Also how does the IP addressing work on 2 sites. The main network uses 10.120.21.x and DHCP is assigned from a cisco router. Does the remote network assign from the same DHCP server or would the remote sites cisco router need to be setup to give out DHCP to local machines. If so what would be the best IP setup to use.

We found out that only local multicast ip address range is not passing between the sites, any other range is passing, local range is 239.0.0.0 and above.
We have two different datacenters, the internal switch is 2960S (Stacked) with 1-10 vlans and the external switch is 3560E, the external switch is adding another tag (qinq, dot1q), vlan 611, and send the packets to metro line to the other site.
on the other site we have the same configuration.
internal switch from site A is configured with igmp querier and the internal switch port on site B connected to the external switch is configured as mrotuer port.
multicast and igmp is passig between the sites, but the local multicast range is not passing, igmp filterring is configured on all port but no profile is defined and no ports are filterred, on the external switch igmp snooping is disabled.
I have 3 3560 switches which are configured with trunks between them. They run vlan 10, 11 & 12. I have a 'core' switch (switch 1) of these 3 to which an MPLS router is connected on vlan12. I in addition have another switch hanging off the 'core' switch via a routed link (switch 4). I have EIGRP configured as a stub and as such the IP address on the routed link at the core switch end is of a /24 from v lan 1 on the other switch. This makes the route directly connected and therefore distributed via EIGRP stubs. Switch 1 is then exchanging routes with the MPLS router (via EIGRP).
The problem I have is that from any sub net on any switch (switch 1, 2 or 3) I can ping 192.168.13.1 (switch 4). When I try and ping switch 4 from over the MPLS I am unable to. If I trace to the switch I see it reaches the outside of the MPLS router, but is then unresponsive. The same applies if I try to ping switch 1 on 192.168.13.2. Any of the other IP addresses of switch 1 respond.
The MPLS network is a managed solution to which I have no access. I'm told that the MPLS provider is able to ping switch 1 & switch 4 on the 192.168.13.x addresses from a remote router (192.168.32.2). I have tried from a switch on the same L2 sub net (192.168.32.1) and I don't get a response.
From switch 4 I am able to ping the switch on 1 of it's interfaces (192.168.19.1), but not the interface I mentioned above 192.168.32.1. There are no access lists in place on the switches and no firewalls between the sites.
We have a number of sites which have high-speed L2 links which terminate on our L3 switches at each site. The ports are between the sites are placed in routed mode.
I would like to use Jumbo frame between two of the network which will communicate across sites and 1500 mtu on the rest, is this something which is possible?
From my understanding is the mtu is set on the interface therefore if I set the mtu on the L2 link ports on both sites to 9000 then would this cause a problem for the 1500?
we've had an issue with our network, we have 2 6509 connected with redundancy, which are connected with 2 x 4900 Switches, from which are connected to a ESX Chassis for visualization, the thing is that the ESX stopped working, and the 4900 switches, and the main core were suffering from overload, they hang on it very well, in order to stop the overload, one of the links to the ESX Chassis were disconnected from one of the 4900 switches. The CPU usage from the 4900 and the core(6509) went down below 40%, and then they started to migrate the virtual servers from the chassis to another 2 chassis that were added right after. They were actually working well, but suddenly the 6509 changed to the other supervisor after everything was OK. We were wondering what could have been the cause of this, maybe the virtual servers migrations, maybe the overload from the ESX ? We also had a few question, is there any need to reload the cores every few months as a planned task ? Because the cores have been up for more than 1 year. And also is there any kind of of tool to monitor the CPU status, or the status overall from the cores or the switches ?

If client gateway = 192.168.64.9 then next-hop = 192.168.64.8 else use default-route 0.0.0.0
I know it's possible to do a route-map match ip-address ACL list. But is it possible to match on gateway?
Some info about hardware and config:
6509-E in VSS (IOS 12.2(17r)SX5) withVS-S720-10G supervisor.
All routes are static, IP for 192.168.64.9 is on SVI vlan.
I have two ISPs. Each is on it's own subnet connected to the 6509 MSFC/Switch. FW1 is on 100.1.100.0/30 and FW2 is on 200.1.200.0/30 subnet. My goal is route all traffice going to the Internet from subnet 10.133.3.0/24 to FW1 and all other subnets across the organization to FW2. I am not sure if I need to use ACL / Static route combo, or just a static routes or ACLS?

View 11 Replies View RelatedI would like to ask you if it's possibile to block routing between some Vlan for just once of them.
Maybe I can explain better:
I've got a Cisco 6509 with 4 configured vlan interfaces
Int Vlan 10 10.10.1.0/24
Int Vlan 20 10.10.2.0/24
Int Vlan 30 10.10.3.0/24
Int Vlan 40 10.10.4.0/24
Vlan "10" is the phone voip Vlan and it must not talk with the others Vlan. The others Vlan can comunicate normally except with Vlan "10".
Pratically Vlan "10" needs to be isolated from the others.
This equirement comes becouse Vlan 10 is wireless and has the WEP key encryption (very weak protocol). Some Phone couldn't support the WPA2 key and I need to avoid an unauthorized external client, cracking the WEP key and connecting to this WiFi, could have free access to the others Vlan.
I have a problem on my catalyst 6509 on which I would like to do the following things :
I have some Vlans in which multicast is enabled.
In tose Vlan theres is a router which is default router for equipements.
I had enabled multicast routing because some Vlan needs to exchange multicast informations, but I wolud like to make difference between Multicast traffic. For example I have 5 vlans:
Vlan 1 and 2 need to exchange Multicast informations but the don't need multicast information from Vlan 3 and 4
Vlan 3 and 5 need to exchange Multicast informations but the don't need multicast information from Vlan 1 and 2
Vlan 5 is independant Vlan but doesn't need to have multicast information from all others vlan.
Last problem, equipement on differents vlan can use the same Mulkticast group address. In this case, Multicast routing is not working between Vlan 1 to Vlan 2 and Vlan 3 to Vlan 4.
I need to setup my 6509 with PBR going to two different Firewalls. The 6509 has vlans and multiple serial interfaces. What/where do I install the policy-maps? I want to direct one of the vlans to one firewall and the other vlans and wan subnets to the other firewall.

Customer restarted the core so we lost all the log files and couldnt find out any root cause on the same. TAC engineer suggested to have some script configured on the system in case of CPU shooting up above 70%, it will create a file in flash and keep appending the logs to the same. Last week i got call from customer saying that the CPU again went high for around a minute on both the cores. Last time i added CoPP also on the switch in order to prevent the CPU reaching 100%. Still it went high and from the captured logs i saw that the process created the high CPU was Port Manager Per and SSH process. Attached the file created by the netdr capture command.

View 3 Replies View RelatedWe have connected a single F5 box with dual links to 2 different Cisco Catalyst switches using 802.1Q trunks. F5 is configured with RSTP mode and on Cisco Switch RPVST+ is configured.STP root bridge is hardcoded on the Cisco side. Loop Guard is globally enabled.On F5 STP link type is Auto, STP Edge port is disabled since that port is connected to the cisco switch.When we are failing over the F5 primary link to the secondary link we see 'Loop Inconsistent' on the cisco switch and things dont work after the failover.We have tried configuring the F5 as STP passthrough but that doesn't fix out the issue.I have checked out the forums and found out following recommendations
1. Configuring MSTP bw F5 and Cisco for better compatibility (Not possible from Cisco side because of a major change in large production setup)
2. Configuring VSS in Cisco switches (not possible due to hardware limitation)
3. Connecting F5 using single links to each switch (redundancy compromised)
I am wondering that on which default vlan does the F5 STP instance0 sends the STP BPDUs ? the term used on Cisco side is native vlan and others use PVIDs; that F5 default vlan should match the native vlan on cisco trunk side.
Tonight we were performing an IOS upgrade on our 6509 VSS to 122-33.SXI6. Both 6509's have dual Supervisor cards installed. Initially we had problems with switch 2 slot 5 supervisor returning to rommon however switch 2 slot 6 supervisor loaded correctly. After manually setting the boot var in rommon, switch 2 slot 5 supervisor reloaded correctly.
After all supervisor's were online we noticed when looking at " show switch virtual redundancy" that sw 1 & 2 slot 6 supervisors were running the correct IOS version but sw 1 & 2 slot 5 were running different IOS versions, however when looking at the show version we are running on the upgraded IOS??? See output below...
Why the active supervisor has loaded the incorrect IOS the VSS is running on the upgraded IOS? I have verified the IOS was copied correctly to each supervisor bootdisk, I see no issues.

We are looking to avoid the need to install an additional device in our network as our core 6509s are not being pushed by any stretch. However, we are having an issue getting the 6509 to assign DHCP addresses and perform NAT.
Most interfaces and V LAN's on the 6509 are using public IPs and have BGP routing at the edge. We have a trunk up link coming into the 6509 on a ws-6816 card via a SMF GBIC in slot 9, port 2 that feeds a wifi link where we are looking to provide guest access to our network.
We created 2 V LAN s on the switch 20 and 21. We assigned a private IP and network to the VLAN20 interface and assigned a new public /30 sub net ip to the V LAN 21 interface. The following configuration was applied which I thought was the required configuration based on how we would typically configure ISR routers for the same services...
ip dhcp excluded-address 10.200.200.1
!
ip dhcp pool WiFi_Pool
network 10.200.200.0 255.255.255.0
default-router 10.200.200.1
dns-server 4.2.2.1 4.2.2.2
[ code]...
What am I missing in this configuration? Note that if I create an access switch port for v LAN 20 on the switch and plug a laptop in directly to the 6509, the laptop is unable to receive a DHCP address. If I assign the laptop an address in the 10.200.200.0 /24 range manually, I can ping 10.200.200.1 from the laptop, however, the laptop will not get to the internet as it appears to be failing to perform nat.
I have a network with four 6509s in a ring with 10Gb links. Two adjacent switches are at the home office, the other two at the DR site. The switches at each location are physically similar to each other with respect to what blades are in them. We went through an upgrade from SUP-720's to VS-SUP-720's recently, only at the DR site - basically a practice, with the home office conversion hopefully taking place next weekend.
We initially just brought up the two chassis separately, in non-VSS formation (stand-alone). So far, so good - everything was connected, all traffic was passiing, all links were up, everything was reachable: EVERYTHING worked. Then we made the conversion: step-by-step from the cisco.com page; create a virtual domain, make one switch switch 1, the other switch 2, create differently numbered port-channels on each 6509, add the SUP 10Gb links to the port-channel, do the conversion.
Here's where the trouble started. First of all, the two 10Gb links back to home office created a spanning-tree loop and we had to shut down one of the links. (Is there something that needs to be configured on those links to turn spanning tree on? Does VSS conversion turn stp off?) Secondly, though it worked while in stand-alone mode, the copper blade in the standby 6509 stopped passing traffic - it would take config, the links would come up, but you could not ping across those links. Interestingly enough, there was an access switch with links to each of the copper blades, and having them both up also caused a spanning-tree loop. adding a new port-channel and putting both links in it did nothing to alleviate the loop. This leads me to believe that stp is not working properly. I reiterate, that even though the loop occurred, nothing else plugged into that blade was pingable.
Will I be OK doing a eFSU Upgrade from s72033-ipservicesk9_wan-mz.122-33.SXI2a to s72033-ipservicesk9_wan-mz.122-33.SXJ1?
I only have a single supervisor in each chassis.
Should I be ok with just following the eFSU upgrade instructions in the below?
