On a 4500 switch having a single sup engine, another sup engine was installed to act as redundant one.the redundancy mode was changed to sso, thereafter the secondary sup was prompted to be reset.
After it came back up again, the redundancy status still shows as RPR in operation mode.
I have installed a WS-X4448-GB-RJ45 on a 4503 chasis. I could not get input or output rate, just shows 0 bit/seg wether or not is forwarding traffic. I would like to know if I have to make any configuration or workaround. The IOS version is 12.2(37)SG1.

View 3 Replies View RelatedMy actual Scenario
1 x 4500 and 1 x 3560?They are gateways of 8 Vlans?They are doing HSRP in each of those Vlans?The 4500 is the Active?There is a DHCP Pool for each of those Vlans on both gateways using "ip dhcp excluded-address" I ensured that the range of provided ips by each DHCP server will not be overlapped Obs.: Reducing the lease time, I ended with the calls bringing related problems.
OK, every thing is blue, every thing is fine.But the network diagram is realy complex(41 switchs, 89 uplinks), and depending of how is the network flow, one or other server answer first or latter.
For many reasons I would like that the secondary DHCP server would answer only if the primary DHCP server goes down.To me, the bigger reason is that DHCP database would be only in one DHCP server.But there is other reasons.
I passed by many frustrated solutions:Try to force a delay on the answer on one of the servers. - Impossible.Try to disable DHCP server, and, using EEM, enable it only if router became active in HSRP. - I couldn't do It.
What I'm thinking now is use the HSRP resource to resolve it.On both routers I would put a "ip helper-address" pointing to an Virtual_HSRP_IP.And depending on which router is the active, him will answer the request.
My first doubt is:Would it work?The second doubt is:Could I use the same Virtual_HSRP_IP that exists on that Vlan(see example 1),or I would need to point it to a Virtual_HSRP_IP in a different Vlan(see example 2)?
Example 1

I have a 6500 chassis with 2 power supplies. At the moment I am using the default configuration:
power-redudancy mode redundant
The problem is that an inserted module is in "power deny" state due too insufficient power.
I know, that It's not a good idea to change into combined mode (loss of redundancy), but my customers requested this anyway.
So I will change to combined mode. So here's the 1 million dollar question: "Which modules will go into power deny, if one of my power supplies fails?"
The 6500 config guide states:
"Power supply is removed withredundancy disabled
• System log and syslog messages are generated.
• System power is decreased to the power capability of one supply.
• If there is not enough power for all previously powered-up modules, some modulesare powered down and marked as power-deny in the show power oper state field."
Well, do you know if there's any way to configure some kind of priority? E.g. I definetly don't want by 10Gig Module or WiSM module to be in power deny. Can i statically make sure, those module will be powered on for sure? Like: "power enable module slot_number" How is this calculated? Or is random?
I have a 4510R+E switch that won't change to the SSO redundancy mode. After entering the 'mode SSO' command, the switch reboots the peer supervisor (as it says it will), but after it comes back up it remains in RPR mode. I've tried rebooting the peer supervisor manually, rebooting the entire chassis, manually power cycling the entire chassis, and reseating the sups, but the switch remains in RPR mode. The issue started when I swapped the switch's supervisor with the supervisor of another 4500. The same issue was observed on the other 4500 as well, but after several reboots, I got it to change to SSO mode. Prior to the swap, both switches were running in SSO mode just fine.Since we're running IOS version 15.0 with the 'spare sup' license, I suspect the issue arose because of licensing complications (with relation to the chassis serial number and the like) when I swapped the sups....although this doesn't explain why the other switch changed to SSO after some troubleshooting.

View 3 Replies View Related wether the Cisco RV180 router model can be configured with a public IP address on the LAN interface? I'm planning to use it in the following setup:
Internet ------------- WAN port (public IP) RV180 LAN port(public IP)-------------- WAN(public IP) RV016 LAN (private IP)
Disabling gateway operational mode and switching to router should disable NAT and allow this setup but need to confirm if it works? I'm concerned if the web management interface actually allows a public IP to be set on the LAN side.
I have connected my 2504 to a 3560 switch via a UTP SFP on a Gig port.
I have my management on 10.0.0.x I have tried tagging the port and untagging.
When I connect to the 3560 the interface comes up a-1000 a-full but when I look on the WLC the port I am using, port 1, shows Link status down.
The green light is on both the WLC port and the 3560 port but I cannot get the link status to come up on the WLC nor can I ping the WLC.
It must be something dumb I have missed.
The WLC port is autonegotiate too.

And the configuration was simple enough and tested fine for redundant static routing: [code] Then I tried to do the same on a 3560 switch running 12.2(55)SE3. ip sla went in fine. But when I went to put in the track I was presented with "list boolean and" (for example) after the track and the identifier.I tossed in the ip sla "10" as the object. But shopw track shows the boolean AND as down. I don't get why the track feature is different in two switches so close in IOS version. How do I get the 3560 to track the ip sla as my 3750 does?

I'm not sure why the guest net work is unsecured. I would have thought that would not be an option but it is unsecured. How to secure the guest network [2.4 GHz]? Also when I view the guest list some devices stay displayed whether they are in the vicinity or even turned off. That adds to my paranoia with the guest network being unsecured. I also can't edit the screen names to know who the device belongs to like is available in "my devices", forcing me to keep a MAC address list.
View 2 Replies View Relatedwe'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 ?
View 3 Replies View RelatedI have the following devices :
-1 VM Host
-2 Layer 3 switches
I would like to provide full redundancy for all vlans being used by VM Guests on the VM Host as well as the management vlan being used by the VM Host.I have created two LACP etherchannel connections on the VM Host. Each etherchannel from the host consists of 4 ports spanning a single NIC. One etherchannel connection goes to a trunked etherchannel connection on switch 1, and the other etherchannel connection goes to a trunked etherchannel connection on switch 2.Switch 1 and switch 2 have an etherchannel connection between them that carries all of the vlans in the topology.Vlan 2 is the managment vlan. Vlans 3, 4, and 5 are vlans that VM guest systems will be using for normal data traffic.
I intend to use switch 1 as the VRRP active router and spanning-tree root bridge for vlans 2 and 3.I intend to use switch 2 as the VRRP active router and spanning-tree root bridge for vlans 4 and 5.The spanning-tree configuration is using multiple spanning-tree with two instances. Instance 1 has vlans 2 and 3 associated and Instance 2 has vlans 4 and 5 associated. I would like to have this topology be fault tolerant to the point where if one of the etherchannel links between the host and one of the switches goes down, (for example, if switch 1 was powered off) traffic will be automatically redirected through the other functional link. I believe that my VRRP configuration would allow for a fairly quick failover of layer 3 services, but I am not certain that my design will be functional at a layer 2 level.
What I am uncertain about is how spanning-tree will converge. I am assuming that the virtual switch on the VM host will not be forwarding any BPDUs being sent by either switch. Would either of the links connecting to the host be considered a redundant link by either switch?Would the link between switch 2 and the host be inactive for all vlans in MST instance 1 during normal operation?Conversely, would the link between switch 1 and the host be inactive for all vlans in MST instance 2 during normal operation? Would all links remain active for ALL vlans? Would this mean that some traffic may travel through switch 2 to reach switch 1 instead of going directly to switch 1?

How to setup redundancy on a 2800 series Router so that whenever it fails it will be routed through the MPLS router
View 5 Replies View RelatedI received the following info from Cisco's TAC and wanted to inquire further before I start reconfiguring the switch:
In a redundant Sup-6E setup, the following configuration is supported :
- 1 TenGig uplink on Active Sup and 1 TenGig uplink on Standby Sup
- 1 TenGig uplink on Active Sup and 2 Gig uplinks on Standby Sup
- 2 Gig uplinks on Active Sup and 1 TenGig uplink on Standby Sup
- 2 Gig uplink on Active Sup and 2 Gig uplinks on Standby Sup
If you invoke shared backplane mode, the following configuration can also be supported:
- 2 TenGig uplinks(blocking) on Active Sup and 2 TenGig uplinks on Standby Sup
- 2 TenGig uplink(blocking) on Active Sup and 4 Gig uplinks on Standby Sup
- 4 Gig uplinks on Active Sup and 2 TenGig uplinks(blocking) on Standby Sup
- 4 Gig uplink on Active Sup and 4 Gig uplinks on Standby Sup
Here's the command and information about the "shared-backplane" mode :- [URL]
Currently, we have 2 SUP 6-Es(Module 5 - Active and Module 6 - Stand-by) setup in a redundent mode. I am planning on changing the redundent mode to the shared backplane mode so I can use 2 TenGig converters to uplink 2 access-switches. We purchased 2 TenGig converters and here is how I am planning on using them:
1- One will be used to uplink to two 3750 switches(stacked)
2- One will be used to uplink to a 2960 using a Gig SFP
My questions are:
1- Do I have to install the 2 TenGig converters(4-Gig Uplinks) in the same Module? Or can I use one one in module 5 and the second one in module 6?
2- Will changing the redundant mode to the shared backplane mode require rebooting the switch or disrupt the funtionality of the other linecards?
Can any share some useful links on how this works and how to configure it? Do you still need to configure FHRP or does configuring redundancy take care of active/standby relationship between the ASR's?
