I am going to change a running 6500 switch. I am missing a best pratice doc for changing a cisco switch configuration. My question is if a startup-config has an error (due to typo mistake, or due to comands not supported on latest IOS) and I do copy tftp startup-config then what will happen ? I want to make sure when I do "reload" the switch then it should boot normally with the latest startup config !
View 3 RepliesWe have two 6500 core switches and one(primary) of them is running in VTP transparesnt mode and the other (secondary) one is running in VTP client mode. I would like to change the VTP mode of the second switch to transparent mode. Would it cause any issue. I guess i have to create VLANs onto the switch.
View 7 Replies View RelatedWe have two 6500s. One is running in power redundant mode and the other is running in combined mode.We need to change the one running in combined mode to redundant mode to ensure it can run ok on one supply if needed but I have a couple of questions.
1. Assuming that we are not oversubscribed on the power allocated, does changing the mode cause any disruption?
2. The switch running in combined mode seems to have allocated some power for an "Inline Local-Pwr-Pool" which is not allocated on the switch running in redundant mode (see attached). Does this allocation will be needed if we change the power mode?
we have 6500 series switches by default all port channel loadbalancing is src-dst-ip.Now we have a requirement to change LACP load balance method to src-dst-port.
1) If we change LACP loadbalance method whar are the effects we are going have on our core network and all the existing servers
I have a pair of data center core 6500 is running a single EIGRP AS with the standard core redundant cross connects. Recently an SVI sub net was expanded from a /24 to a /23 and dropped out of the EIGRP routing table. Subsequent trouble shooting lead to the router id being one using an IP address that is no longer active IP address.
Reviewing old configurations I found, that year ago, the ip address used for the EIGRP router-id (10.100.106.3) was removed from the active interface and changed but the EIGRP router-id was not updated. The switch has not been rebooted since, no loop back is configured and there is not a higher IP configured on an active interface. Reviewing documented material on it, I cannot find anything specific on this condition but do see in the discussions on duplicate IDs, that new route updates can be a problem. I know how to update the router id but I am looking for confirmation on what would be the impact when I add a new loop back and manually configure the router-id under the EIGRP process with the new loop back IP.
My assumption is an EIGRP update and route re convergence with the standard 90 seconds of outage. How to confirm this is assumption is correct? I have no test bed to find out myself without doing this on the active cores.

I am installing a several new Cisco VM servers. The VM hosts are losing connectivity when we apply the etherchannel config in the core stack. VMware has stated that the etherchannel load balance needs to be src-dst-ip in order for the etherchannel to work.However, my current stack has 2 etherchannels configured to other switches through out the bldg in network closets. The current load balance configuration is src-mac.My question....when I make the change to src-dst-ip, will my network connectivity go down? I saw there was an older article on this that doesnt provide an answer just a work around. Here is the article. [URL].
View 1 Replies View RelatedI am having trouble after creating a management vlan (99) on a 3550 switch.I have configured the vlan (99) and given it an IP (192.168.1.100) and a default gateway (my router address - 192.168.1.99).I can ping to the switch from a PC and vice versa. The management VLAN IP is fine but now I cannot ping to the router from either the PC or the switch.It seems that just by adding VLAN 99 with it's own IP address has now prevented pings from the switch/ PC to the router ?Due to the fact that I have created a new switch management VLAN with an IP, does this mean I have set up the router as a 'router on a stick' scenario ?

2) I am in process of changing switch member number from 3 to 2 , I executed the command on the global config mode " switch 3 renumber 2 "but I yet to reload the switch .
here I have I doubt . as currently the ports module are fas 1/0/1-48 and fas 3/0/1-48 under respective vlan . once I reload the switch is the switch port module number will get change to fastethernt 3/0/1-48 to fastethenet 2/0/1-48 ??? . if it happens the vlan configuation which configured on the fas 3/0/1-48 module also get configured automatically or I need to configure manually
3) as i said i have execuated the command : "switch 3 renumber 2 " , how to remove this or revert the change , as i checked in the running config this command not exist .
switch ( config) # switch 3 renumber 2WARNING: Changing the switch number may result in aconfiguration change for that switch.The interface configuration associated with the old switchnumber will remain as a provisioned configuration.Do you want to continue?[confirm]Changing Switch Number 3 to Switch Number 2New Switch Number will be effective after next reboot

Notebook >> (access vlan 100) SW2960 (trunk)>> (trunk) C6500
First time I have create SVI interface on C6500 and enable trunk on interface that connected to SW2960 and SW2960 assigned access vlan 100 on port connected to Notebook. Then I tried to ping from Notebook to C6500 on SVI100 which work fine.
Second time I tried to enable MST on C6500 and after that everything still working and I can ping from Notebook to SVI100 on C6500.
Third time I tried on turn on dot1ad in global configuration mode and from now I can't ping from Notebook to C6500.
Forth time I tried to disable dot1ad from global configuration by "no dot1ad" command and then I can ping.
My intention is I would like to do EVC which require dot1ad in global configuration but I stuck in third step and don't know what's does it mean for this command and how I can resolve this issue?

I am trying to guarantee 100mbps for a vlan across a gig link. I have done some research and found this command for switches
mls qos srr-queue input priority-queue 2 bandwidth 20
However it doesn't seem to work for my 6500. I know the 6500 uses PFC for QOS but I have no idea how it works. how I can guarantee a vlan 100mbps across a 1gig link?
I have a pair of 6500's setup with VSS and there is currently only one link between then. However one end of the link is on Po10 and the other end is on Po25. If I move the Po25 over to Po10, will things break? It seems to be working fine now. I'm about to add a second link and I'm concerned about the current configuration. It makes more sense to me to have both ends of the same link on the same port-channel ID. I've seen documentation which states otherwise however.

I have seen conflicting information regarding downtime for this upgrade process and still have questions after reading URL. In this scenario, we have a VSS with one SUP in each chassis.
Are the chassis or modules rebooted one at a time? For instance, if I issue an "issu loadversion", will this just load the code on the SUP in the standby chassis, or will it load the code on the modules as well? If it does load the code on the modules, then I will have to wait the longest time from the "show issue outage slot all" before issuing a "issu runversion", correct?
Also, what outage times have people seeen on modules that support pre-loading? I have not been able to find any documented information on this other than it is faster, and the link referenced above still shows a 5 minutes outage for a warm reset on one of the modules.
