Cisco Switching/Routing :: 6509 / Provide Internet Redundancy To Local LAN User Running In HSRP?

May 7, 2013

One of our customer ,  where there 2 6509 switch , one is Core_sw1 and other is Core_sw2 , catering about 32 Vlan , and HSRP in running for all Vlans , till here no problem , now there internet Router which having one Internet link , which connected and configured on Core_sw1 in a way that one interface of Core_sw1 is given Public IP and there is vlan 85 which internet vlan and vlan 85 ip are natted with that public IP with one simple static route given toward internet router , this is how internet is working ok.
 
Now i have configured  vlan 85 in hsrp as all other are , how can give redundancy to vlan  85 user , that if Core_sw1 get down , internet traffic can get out through Core_sw2.using same internet router with single internet link .i am not talking of ISP redundancy , but Vlan 85 in Core_sw1 goes down , other Core_sw2 will server internet.

Cisco Switching/Routing :: 6509 - 802.1x And Voice VLAN / Enable Dot1x On User's Ports On The Switch

Sep 17, 2012

I have a Cisco 6509 with IOS "s222-ipservicesk9_wan-mz.122-18.SXF16.bin"I need to enable dot1x on user's ports on the switch. each user is connected to the switch through the IP phone.
 
I just found out that I can not enabled dot1x on trunk port. I have tried to use "switchport voice vlan " but I got:
 
Switch(config-if)#switchport voice vlan 123
Command rejected: Gi7/20 is Dot1x enabled port.
 
let me know what should I do to get dot1x working?
 
Note: I have connected a laptop directly to the port and dot1x is working fine.

Cisco Switching/Routing :: 6509 / HSRP Migration To VSS With 0 Downtime?

Mar 13, 2012

I have to migrate two Cat6K series switches in a Data center to the new Cisco 6509 Series switches with no downtime. i know there are few threads on the same topic but none of them discuss about the downtime.The two Old Cat6K series switches are working in HSRP redundant mode. All access/Dist switches are dual homed to these two switches in downlink direction. In the uplink direction a router is dual homed to both Switches. Now my requirement is to completely migrate the configuration from the old switches to the new one in VSS mode without any downtime. Already VTP server is running on of the old switches so VLAN migration is not an issue. I will update the network diagram in few hours .As per now i am going to follow these steps:
 
1. Remove active links from switch 1 and shut it down
2. Monitor network and traffic impact on switch 2
3. Install the new 6509 switch along with switch 2 (VSS config already done in Staging)
4. Config HSRP and make it standby
5. Connect all removed links back to new switch
6. Remove old switch 2 and monitor network
7. Connect new switch with VSS config
8. Connect the two new switches together in VSS and move virtual IP to SVI.
 
During last step i think i will face some minor packet drops.

Cisco Switching/Routing :: 6509 - HSRP Standby Address Not Reachable

Jun 11, 2013

I have  my hsp setup where switch A and switch B share active/standby roles among several vlans. In the last few weeks, i have seen trouble tickets where connectivity is lost and upon investigation i discover that i can ping physical interface IP addresses for both standby and active devices but not the standby IP. I have also validated configurations and layer 2 paths and they haven't been broken.

What I end up doing is failover to the standby device and back and the problem clears, reachability is restored. My question is whether I am solving this the right way. If so, what is it that would cause the standby IP to not be reachable and how does my solution fix that? N/B the switches are catalyst 6509's.

Cisco Switching/Routing :: 6509 - Doing IDS Via SPAN Ports

Dec 13, 2011

I am hoping you can provide me with some opinions, feedback, thoughts on the following. We have some Cisco 6509 switches in our environment currently hitting around 60% usage on the Router overall statistics.
 
Now we are looking at implementing an intrusion detection system but by being as least invasive as possible to the network. Our thoughts are to utilize a SPAN port on the switches to send traffic to the NIDS device but we have concerns of the following. The limitations of SPAN sessions on 6509's . The overhead on the switch of turning a SPAN session on and leaving it on permanently.

I  want to give limited access to our first level support so that they can execute certain basic commands like, port vlan change, access port shut/no-shut on Cisco 6509 and 3750E switches IOS based. I want to restrict them to only few options so they can not make changes to uplink (TenGig) ports and can not issue reload command etc. We do not have TACACS. What is the best way to achieve this?

Cisco WAN :: 3750 L3 / EIGRP Load Balancing While Running HSRP?

Dec 15, 2010

I'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?

Cisco WAN :: 6509 - 10 Gig EIGRP Metric

Oct 3, 2006

I have recently connected a 10 Gig connection from the local telco between two sites on 6509's.  These two sites also have a 1 Gig links between them.  When I connected the 10 Gig link I expected the 10 gig link to be the preferred route, but after looking at the routes I noticed that both links have the same EIGRP path cost. Also the minimum BW for both links is 1000000Kb or 1Gb. Why?

Cisco Switching/Routing :: 7609 For Switching / Based On LAN (VRRP / HSRP) Feature

Oct 18, 2011

I am facing an isssues with 7609 for LAN switching , based on  LAN (VRRP/HSRP) feature.Actually  we are having ES+ cards (on 7609) and we are using multiple groups(say  350 vrrp groups) running on the router . the routers are connected as router 1>>> mux(which is working as switches)>>> router2

my questing are

1.  does their will be "multicast packets" (for VRRP/HSRP group) "from backup  router to Master router", when in stable state( ie when Master and  backup are already chosen) , or the packet from backup to master should  be unicast.I know for sure, the packet from master to back is multicast packets denstination to Multicast IP packet and To MAC address.I am not sure but I think from backup to master it should be multicast
 
2. what is frequency of these packets( from backup to master)
 
3.  As i have multiper group on a single interface ( we are using q-in-q),  when the connectivity from router's is broken, then does all the groups  will muticast their active roll in the lan sengment "at once" or it will  be in a groups say 100 groups at once, and after few ms few 100's and  sone ( as is on OSPF or RIP)
 
we are in between troubleshooting I hope we get the ans( Actul problem we are seeing in the router's that we have 2 ports on active routers and 2 ports on standby router , but we are not seeing muticast on 1 port on standby router where as all other 3 ports are seeing multicast packets) [code]

Cisco Switching/Routing :: GNS3 - Stub Router Not Updating Routing Table - EIGRP

Nov 14, 2012

We have small which I'm looking to implement and have built this on GNS3.
 
We have:
 
Router A in site 1
Router B in site 2
Router C in site 3
 
Router A and B are connection via a point to point 100M link and from Router C we have a 2 point to point one of which is 5Mpbs and going to Router A and Router B.
 
For Router C to reach Router A network it will go via Router B and these are 100M connection. When the link between Router A and B goes down. Router C should update and start using the 5m route.
 
For some reson, the routes are not updating. I have to do 'clea ip eigrp ne' for the routes to update and if I reload the routers all works well, it seems the problem is intermittent.

Cisco Switching/Routing :: 3560E - HSRP Gateway Failover And Routing Table

Nov 12, 2012

We have two Cisco 3560E layer 3 switches at the core of our network. The switches are configured as an HSRP pair and the clients on our network point to the HSRP address as their default gateway. So if CORE-A dies, then CORE-B will pick up the address and the default route for the clients will continue to be available.We also need to specify a few static routes on the core switch to allow us to get to specific networks. Is there a way to do this so that the routes failover in the same way that the default gateway does?

Cisco Switching/Routing :: 891W ISR / Can't Get SSID To Broadcast

May 27, 2012

I'm working with some 891W's that have the internal 800-series AP. I have this router set up initially using Cisco Config Express, then, using Cisco Config Professional 2.5 I set up the firewall and other featuress that CCE doesn't do.  Overall this is a very simple router, meant to be a small business Internet gateway device but is currently in my lab. 
 
The intended WLAN setup is very simple.  One SSID, with broadcast enabled, using WPA2-Personal.  Auth: open  Encryption is both TKIP and AES-CCM. 
 
However no matter what I do I cannot get thhis thing to broadcast . In the past I had sometimes run into issues where if I had more than one AP running independently it would cause a channel conflict and one or both would cancel each other's radio, so I disabled all other AP's in my vicinity. 
 
Also I've had issues in the past where f I enabled both TKIP and AES, sometimes clients can't find the AP as a result.  My solution had been to disable one of them leaving just the other - no change here however. 
 
Via the IOS, ssid config shows mbssid guest-mode which I believce is default. 
 
Interestingly, if I do the following:
 
ap# Config t
ap(config)# dot11 ssid <myssid>
ap(config - ssid)#guest-mode
end
 
I end up with both "guest-mode" and "mbssid guest-mode" in the sh run for the AP, and voila, my AP broadcasts the SSID.  However clients end up joining without any security at all, no prompts for pre-shared key or anything.

Cisco Switching/Routing :: 6500 - HSRP Design And VSS

Apr 17, 2012

is it possible to run hsrp on two routers (not l3 switch) connected to a l2 switch ? if so does the two routers need a back to back connection ?
 
i know if use two l3 switches (instead of routers) and connect to a LAN switch then we need a back to back connection between the L3 switches
 
also can we use hsrp on vss on 6500?
 
design
 
 
1800 router                                       1800 ROuter
     |                                                        |
     |                                                        |
     |---------- L2 switch-------------------------------|
 
if the above design is acceptable how does the routers know which one is active and which one is standby ? if we need a direct connection between two routers they have to be on a seperate subnet and routers dont allow broadcasts - so how will hsrp work on routers ?
 
L3 switch --------------------------l3 switch

Cisco Switching/Routing :: 3560x / HSRP On LAN And WAN Interface?

May 9, 2012

I currently use L3 switches as edge routers to my WAN. I want to use a pair of 3560x switches with IPbase to provide a failover path to my WAN using HSRP at one location but had some problems testing the configuration. My plan is use a virtual address on the LAN interface (VLANx which port gi0/1 accesses) and the WAN interface (VLANy which port gi0/24 accesses). I want switch 1 to be primary since it will have an IPS attached to it, and switch 2 will be backup and used only when switch 1 or the IPS requires maintenance. On both the LAN and WAN sides there is no advanced routing going on, the various hosts just depend on the availability of their respective default gateways, so HSRP should be sufficient to provide a failover in either direction.
 
In my testing I got 1 or the other link to fail over but not the entire switch. What should my config look like to achieve failover of the entire switch in the event 1 or the other interface goes down, and fail back when the primary links are again available?

Cisco Switching/Routing :: 6500 - HSRP Is Instable

Apr 14, 2013

n our datacenter we've implemented HSRP on 2 6500's for redundancy purposes. Both switches are connected via a trunk. When an interface is administratively brought up, HSRP becomes instable. Below some selective logging: 
 
12:58:01.759 CET: %HSRP-5-STATECHANGE: Vlan32 Grp 32 state Standby -> Active12:58:01.919 CET: %HSRP-5-STATECHANGE: Vlan21 Grp 21 state Standby -> Active12:58:02.031 CET: %HSRP-5-STATECHANGE: Vlan42 Grp 42 state Standby -> Active12:58:02.031 CET: %HSRP-5-STATECHANGE: Vlan18 Grp 18 state Standby -> Active12:58:02.223 CET: %HSRP-5-STATECHANGE: Vlan4 Grp 4 state Standby -> Active

Basically what happens, is that both switches becomes active and thus are forwarding traffic. After a few seconds all is back to normal. It seems they are missing each others "hello messages", so the state change is in this case normal outcome. What I can't figure out', is the root cause. Since it is triggered by bringing up an random interface configured as a dot1q trunk, I'm thinking of STP limits. But the limitations I found are 10.000 active STP logical ports and 1800 virtual ports per slot. In my case this is 2591 logical ports and all the virtual ports per slot are below 1800. This suggest the switch is capable of running this set-up without a problem.
 
Some extra information:-Sup 720 10GE-Version 12.2(33)SXH2a-No Vss used-No drops on trunked interfaces between the 2 core switches-83 standby groups (max256)
