Cisco Switching/Routing :: 4500 Standby Sup In Disable Mode
Aug 3, 2012
I have a Cisco 4500 as my core switch and there are two sup eng in this core. However, I noticed that the redundant sup is in diable mode rather than Hot Standby.
I have tired to enable the module but I am not able to do that.
I have issue with my 4510 switch which has got two supervisor engine in single switch.
I am trying find the root cause but not able to ....
Standy supervisor engine is not detecting ....
In show module and bootvar output also , there is error saying " Standby is not up "
show module ouput :
Switch-4510#show moduleChassis Type : WS-C4510RPower consumed by backplane : 40 WattsMod Ports Card Type Model Serial No.---+-----+--------------------------------------+------------------+-----------1 6 Sup V-10GE 10GE (X2),
I went through the configuration guide for 4500 series switches for NSF/SSO for failover between Sup's. I just wanted to know that that are we supposed to run the SSO command on both of the supervisors? Secondly, are we only supposed to run the nsf process under EIGRP on the secondary supervisor and routing peers and not on the primary supervisor?
Can you confirm that if I want to disable temporarily a dhcp pool on a 4500, I need just to shutdown the interface VLAN corresponding to a specific dhcp pool?
ip dhcp pool test network 10.X.27.0 255.255.255.0 default-router 10.15.27.250
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 stacked WS-C3750E-24PD with Ten Gigabit Ethernet ports configured under ether-channel. It has c3750e-universalk9-mz.122-55.SE1.bin IOS installed on it. One of the Ten Gigabit Ethernet ports, goes to err-disable mode with following errors on that specific ports.
I am using radius authentication on C4507R+E with supervisor card 6L-E and IOS 15.0.2(SG1). It works perfectly but all radius messages appear in the console. Radius is very verbose, I can't use console because of the significant number of messages and I am worried about switches performances. I add that all debug commands are disabled.
I 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?
I've got an ASA which has a number of contexts. They all share the same external interface, and in the interest of saving addresses I'm wondering if the standby address for each context is really necessary. I know that in active/passive the standby address is what allows the two to communicate and monitor that particular interface, however, in active/active I don't see the point as the context is either going to be on one or the other.
i do have two 6500 in VSS mode , and one FWSM module on each 6500, i want to configure these modules as Active/Standby, how do i start , should i follow this (not in VSS mode): url..
I have been reading several posts in this forum to try to understand ACL behaviour on a standby HSRP 6500, I would be glad to get this cleared.I have two 6509 running HSRP for all Vlans...I created VLAN 100 with standby ip address 192.168.1.129 255.255.255.128
Active 6509 (SW01) ip is 192.168.1.130/25, priority 120 Standby 6509 (SW02) ip is 192.168.1.131/25
I have created a DHCP server on the standby 6509 only on the same VLAN 100 with a defaul router of 192.168.1.129 (i.e. the hsrp vip). I connected a pc directly to the ethernet port on the standby 6509 and put it under VLAN 100 and it obtained its ip 192.168.1.200 from the ios dhcp.Now I want to restrict this PC (and any other on its subnet) to access only a remote server 172.168.10.10 and nothing else. I have created the following access list, allowing traffic to the remote server, ospf and hsrp updates,ios dhcp...
Extended IP access list SWRES 10 permit ospf any any log (172 matches) 20 permit ip any host 172.168.10.10 30 permit ip any host 224.0.0.2 40 permit udp any host 255.255.255.255 eq bootpc 50 deny ip any any log (52 matches)
I have applied this ACL on both the 6509s under interface VLAN 100 ip access-group SWRES in
1. When I ping different subnets on the 6509s from the PC, I still receive icmp replies although I expected the acl to pass traffic destined for the remote server only. I do get deny log messages on the Active 6509, but not on the standby 6509 where the PC is connected.
2. Is permitting bootpc in the acl enough for IOS DHCP server and client operation? Do i need to explicitly permit access to the defaul-router configured in the DHCP, which happens to be the VLAN 100 gateway ip and hsrp vip as well (192.168.1.129)
3. I do get deny logs on both the 6509s from the PC trying to access the local VLAN 100 broadcast address on ports 137, 138.
%SEC-6-IPACCESSLOGP: list SWRES denied udp 192.168.1.200(137) -> 192.168.1.255(137)
I need to setup an ASA 5525 in Active/Standby failover mode. I am setting up the ASA for a company that purchased only one public IP address. The public IP address is assigned to the outside interface. My question is will failover work correctly if I don't use a secondary IP address on the failover configuration on the outside interface?
We have currently install single ASA 5550 and want to install one more ASA for active standby mode, but cisco discontinue or End of sale ASA 5550. can any one guide me ASA 5555X is compatible with ASA5550 on active standby mode or not.
I have two WLC version 7.3.101.0 with the standby unit having HA-SKU. I have tested the AP-SSO functionality without any problem in lab with direct connection on RP port between two WLC. Once I brought them into data centre in separate location (latency is less than 10ms between the two DC), the standby unity always went into maintenance mode. The booting process on standby unit went to maintenance mode as shown below:
Management Gateway and Peer Redundancy Management interface are not reachable.Entering maintenance mode.
I have checked on the core switches at 2 data centre that the two WLC RP ports are connected to same VLAN and it is spanned across MAN link (10GB and less than 10ms delay). The spanning tree on those ports are forwarding as well.I have rebooted the second unit but no luck.The interface between two DC is using MTU 9216 which I do not think would cause this issue.
We configuring ASA 8.4.2 in Active/Standby failover mode with two cables. What would be the best design configuring etherchannel on ASAs or have one active and one standby redundant cable ?
I am running HSRP on three 4506 switches..S1(active) S2( standby) and S3(listen)..S1 is active for all the vlansRight now, I wanted to make S3 active for two vlans: vlan 10 and 19What would be the impact to the end hosts?Also, can you tell me why the arp is not syncing for all the three devices? [code]
I have multiple 6509 vss switch. and i notice when the standby chassis reboot I didn't get any snmp trap, but I got when the active one reboot. my question is is there any mib out there for detecting and got a trap when standby reboot?
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.
I am working on two Nexus 7010 with 5.1.5 NX-OS version. I configure HSRP traditionnaly, Nexus 1 with a priority of 200 and Nexus 2 with a priority of 100 for all vlan.
When I change the priority of a vlan to 200 to 50 for example, Nexus 2 become active and Nexus 1 standby. The problem is that when I do a traceroute from a PC the packet take the Nexus 1 as defaut gateway all the time.....
For information I have a peer link between the 2 Nexus for vPC.
I am a single ASA-5510 with CSC module.I want to pair it for active/standby mode for failover .... can it be done if second ASA doesn't have the module? Can I assume the in case of a failover, the traffic won't be checked, and primary does in case CSC module fails?
I have 2 6509 chasis with one SUP720-3B in each and current IOS is s72033-ipservicesk9_wan-mz.122-18.SXF4 and 2 FWSM with version is 3.3.1 I need to upgrade FWSM system software to 4.1, after checking FWSM 4.1 release notes, I thought of upgrading IOS to latest version to 12.2(33)SXJ.I got new 2 CF of 512MB and downloaded the new IOS on them and need to upgrade 6509 IOS first to meet the requirement for FWSM upgrade.
We are expanding out LAN network with more 2960 access switches. All the access switches are suppose to be connected to core switch (4507R) but i have less port on the core switch.
On the core switch we have two supervisor engines (WS-X4515 ---description : "Supervisor IV with 2 1000BaseX GBIC ports"). I can see that on each supervisor engine i have two 1 GB SFP ports available and if i calculate for two supervioser engine i will have 4 1GB ports.
But at particular time only one supervisor engine is active and other is in standby mode (redundancy mode used is SSO between two SUP engines).
Can i used all 4 SFP ports for connecting 4 uplinks to the 4 access switch?Will all the 4 SFP ports active at one time or only 2 SFP ports will be active that is for only active supervisor engine.
I was upgrading IOS on 4507 R with dual supervisor.I download the IOS on Active supervisior and did reboot.After reboot i login to switch then i got switch standby prompt.I found that after reboot active supervisior became standby supervisior.
Now new IOS is on standby supervisior.Need to confirm below..So this means that IOS does not syn within the supervisiors as compared to config right ?
-Which command i can use that will copy IOS from standby supe to Active supe?? -Which command i can use that will show both active and standby supe with new IOS? -Is there any command that i can use to switchover from active to standby supe??
After rebooting a pair of 6504's configured for vss, both switches show active on the sup modules. A show switch virtual redundancy however shows the pair working in an active/standby mode. We have 6509's in vss pairs and they show active on switch1 and standby on switch2 led's. For the 6504's switch 1 was booted first and then the second switch about 30 seconds later. Is there something different with the 6504's? [code]
Does the 4500 support VSS (Virtual Switching System) ? On the official product overview page it says: 1.6 Terabits capacity with Virtual Switching System (hardware-ready)What means Hardware ready ? Does it mean that it supports VSS in the same manner as the 6500 ? The reason I'm asking this question is that I didn't find any info on the Internet about this. We would like to upgrade our network by interconnecting the 2 sites with Layer 2 redundant links (Layer 2 extension), but I'd like to use the both links in a load-balancing manner, which can be a real pain in the *** with STP. The choice is between 4500 and 3750 stackable core switches. The 6500s are very expensive.
