Doing a bug scrub on our dual core, dual Sup 720 6500s tonight. We are going from s72033-advipservicesk9_wan-mz.122-33.SXI4a.bin to SXI9. I want to get a second set of eyes on my script since I have not done this for about 1 1/2 years. Following this doc:[URL]
Script:

We 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.

I am planning to migrate the core switch from cisco 3750 to Cisco catalysts 6513 switch. What could be the best approach to minimize the downtime or avoid disrupting the production. I have couple of thoughts, one method is to build the core and then replace the existing core, another option is to build the new switch as the second VTP server and once it recieves all the VTP information then disconnect the old server.

Is there any challenge to upgrade core switch 6500 series from Nexus 7009 which runs NxOS, because i have 3750X series switches connected at distribution and access layer in my network topology??
Is there any challenge if we place NxOS in core and IOS in distribution and Access layer??? how we are able to match sh run config in existing 6500 switch to Nexus 7009 NXOS?

The customer has 4 6500 switches. 2 Physical locations, and 2 switches at each locations. The locations are connected via 1 200mpbs metro ethernet(layer 2). We ran into an issue during a DR exercise. We had created a VLAN for DR testing purposes, that did not have any SVI configured, but the VLAN did exist on one of the 6500s. When the customer restored a VM to the DR VLAN, we lost connectivity to the production server. After some troubleshooting, we found the cause to be the same mac address showing up, but in a different vlan. Once we removed the DR vlan from the 6500 all was well. It seems like switches are ignoring the VLAN in the mac address table, and forwarding to the incorrect ports. The switch is not reporting any mac flapping in the logs. No spanning tree topology changes are occurring. Code version is 12.2(33)SXJ2 on all switches.

I have 2 servers, one active, the other standby, both will be using the same IP. If the active fails then a re-patch for the standby to make this the active. I understand that i will need to clear the arp & maybe mac address table on the 6500 for the new active server to work, as the failed server will have its mac address on the 6500,.
is there a way around this so i dont have to clear the arp cache & clear the mac table? [code]

We are facing issue with mac address learnt from different port-channels, Connectivity is like 6500 as core running VSS and 4500 access switches are connected to Core and WLC is also connected to Core.WLC to 6500 PO 60 , 4500 to 6500 PO 32.

We want to configure the "mac-address-table synchronize" command on our 6500 series switches to ensure that the CAM tables on our DFCs are in synch with the PFC on the supervisor modules. url...it is recommended that we disable the routed MAC purging with the mac-address-table aging-time 0 routed-mac global configuration command. What is a routed mac entry? Are there any issues with running that mac aging-time command?
We also plan to run this command "mac-address-table aging-time 14400" to keep our ARP and CAM tables on the same aging time to reduce unicast flooding on our network. Can we run this command with the "routed-mac" command above?

Version 12.2(33)SXI
int vlan 1
description client vlan
ip vrf forwarding A
ip address 10.1.1.1 255.255.255.0
standby 129 ip 10.1.1.2
standby 129 timers 1 4
standby 129 priority 105
standby 129 preempt
ip helper-address 10.1.2.20
[code]....
dhcp requests are not making it to the dhcp server SAME VRF (ip helper-addres is not doing anything.....)extended vrf traceroutes on udp 67 sourced from vlan2 are fine
I am expecting udp unicast packets on port 67 "giaddr" relay packets on the DHCP server generated and sourced by the relay on Vlan1
eg. Mar 1 01:59:06.731: DHCPD: setting giaddr to 10.1.1.1
This exact setup works in our preprod environment with the same code.Only difference is we run Distributed etherchannel on the 6500's where this doesnt work.
Wireshark on the client I can see the requests being sent Going to check it with debug ip dhcp server to check the relay logs out of production hours.
I have seen so many people say it IS and ISN'T supported on this version of the code.e.g. [URL]
I am aware the helper-adddress should inherit the vrf of the interface ip helper-address vrf command is not supported.The fact it works in the PP environment.... could this be due to the Distributed EtherChanel difference? or just some bug....

I have just updated a VLAN interface on my router. I have two 6500's with GLBP configured. The particular interface had a primary and secondary IP address. I shutdown the interface on one router and deleted the secondary address then assigned the orignal secondary address to be the be the only address associated with the interface and enabled the interface and it came right back up...all looks good. I proceeded to do the same thing to the other router and once again all looked good. Now, I am able to PING the devices in the subnet from router, but am unable to ping them from any place else.

We have a Cisco 3640 router running c3640-is-mz.123-3g.bin Switching ports are devided into several VLans. Each VLan has its own IP subnet. We can't ping IP address X in subnet A from subnet B unless we log into the router and ping it from there first. (and then the IP address will show up in "show ip arp" command. Then we can ping X in subnet A from subnet B, and browse web on device X from subnet B, etc. )

last day i went to one client for the installation of C(WS-C4507R+E)
current ios :cat4500e-ipbase-mz.122-53.SG2.bin
there is only one sup engine installed and redundant slot is empty.
I installed one ethernet module in the slot 6 and it get detected working fine. I also want to install one fiber module but that module is only supported by 12.2 54 sg or later ios version.so i need an ios upgrade.
For the ios upgrade I decide to do it through svi interface For that i igive an ip address to vlan 1 (192.168.1.2) and plug cable in gigabit 6/1 and added that port into valn 1.
my laptop's ip is 192.168.1.1 @ this point i faced a rare problem the PING IS NOT WORKING.(switch is directly connected to my laptop).
Then i create another VLAN (2) and add that port into vlan 2 still ping is not getting.last thing i tried is that making that gigabit port into a routed port and result is same.

I'm having an issue routing between vlans. I have vlan 1, and 2. I want to ping something on vlan 2, from vlan 1. I cannot ping from a computer on vlan 1 to a computer on vlan 2. I can ping each computer from the ASA 5505. I get an error on the ASA when I try to ping from the computers. The error is Failed to locate egress interface for UDP from voice:192.168.0.199/137 to 192.168.1.200/137. I can't understand why it even mentions IP 192.168. 1.200/ 137... I reset the unit configuring it from scratch and still no go. I have no given a static route to the out yet.. I need to get inter-vlan routing working first. [code]

In my preparation for my coming CCNA certification I am experimenting with different network configurations. In my test network I am currently working with a "Router on a stick" setup. A Cisco 2611 router connecting a Cisco 2950 switch. VLANs configured on the switch and subinterfaces + dot1q encapsulation configured on the router. Switch only supports dot1q.Router's Eth0/1 is connected to the Switch Fa0/24 port which is also set to trunk mode. I am using a normal Cat5e twisted pair cable to connect the 2 devices.
VLANs are working since I can connect a workstation to an access port for example fa0/2 (vlan2) and get Internet access.I can also ping any of the subinterfaces of the router from the workstation.With the current setup I am not able to ping the switch from the router, or the other way around, so in other words I can't remote manage the switch from a telnet or SSH session with this setup. What I am missing?Just to be clear I am pinging the switch directly from the router (Router2611#ping 172.16.100.2), so please ignore all static routes and OSPF. [code]

We are using CISCO Catalyst 6500 switches as collapsed core/distribution switches (2 layer architecture). I want to connect approximatly 10 application servers to the network. Can I connect the servers directly to the catalyst 6500 switches using WS-X6148E-GE-TX line cards? The other option is to use access switchs and then connect the servers to the catalyst 6500 through access switch(Catalyst 3750).

when I ping another workstation on my local network I should get back it's local IP but instead I am getting an ip address that resolves to somewhere in Germany! In fact if I ping any bogus name, I mean anything, it returns this same address 62.116.181.25. If I shut down my cable modem then everything resolves correctly. And yes I have DNS relay enabled because it seems to be the only way to get the workstations to resolve external sites correctly.

Everything in my network works as a charm. Every host in my vlans can access and ping the internet with no problems. But, my main router does not ping the internet (Pinging either ip "173.194.71.104" or domain "www.google.com" do not work). I don't know how is that possible since my hosts can ping the internet. Below is my main router confiurations

I have a requirement to connect two 3750 switch with 10G speed between two sites with 150km distance. We will lay-out our own fiber (48 core) between two sites. I just want to consult the following:
1. Could i use two core switch 6500 with single mode fiber as a transport equipment?
2. Or i need to use SDH equipment because of the distance concern? If so do i need a repeater?Could i use Cisco Metro Core ONS, which one?
3. Any other option to achieve this requirement?
