I am uploading new configurations to my Cisco 3750 stacked switch and noticed that after the load I cannot log back into the switch because my password somehow was changed. After performing password recovery and getting back into the swtch, I noticed the configuration register was 0xF. I have never seen this before. The config-register command does not seem to be supported to change it back to factory default. The switch is on a ship which has several power hits when they switch power from shore to ship power.Can this cause the configuration register to change? What is the best way to change the configuration register?
View 1 Replies View RelatedLast night I've upgraded a catlyst 6509 (non-redundant), during the upgrade I# run into the problem that the 6509 only wants to boot from sup-bootflash, and that it took an old image from sup-bootflash.I deleted this old image and then the node came into rommon mode.There I did the boot command and refered to the correct image on disk1:Now the boot succeeded. Just in time before I run out of my maintenance window.
I did some investigation and looked into the supervisor (using attach 5 and remote command switch show boot) and detected that it's configuration register is on 0X2101 (This is because I run into problems a week ago because of a corrupt flash disk and changed this in rommon mode , without changing it back, I'm afraid I'm not totally known with the 6509)
Question is now how can I change the configuration register back to 0x2102 without any service interruption (It will cost me quit some goodwill if I have to boot the node for the third time in three weeks)?

I am trying to set up a simple configuration on a Cisco 4928-10G switch running
cat4500-entservicesk9-mz.122-37.SG.bin
All I want to do is to mark all trafic on vlan 3 let's say for this example with dscp af31.
All outgoing trafic to be marked with DSCP AF31.
In pratice If I have 2 laptops connected to access ports on vlan 3. When one laptop pings the other I want to see on the receiving end when I run wireshark the traffic to come marked with DSCP AF31.
I have a 3560 switch with 1 VLAN (VLAN 10) where I need to make ports:
1-10 as isolated (can't contact each other)
11-20 as community (need to contact each other like a normal VLAN)
23 as promiscuous (server that ports 1-20 need to get to)
24 as promiscuous (WAN router where ports 1-20 need to get to and the remote servers).

I have stack of 2 switches 3750?I config etherchannel between them.

I have a laptop with a single physical NIC which I have used the advanced management tools to create two virtual NICs (say vlan 10 and vlan 20) and both are on the same subnet (say 192.168.4.x). One NIC is for normal TCP/IP traffic and one is for broadcast/multicast traffic (I have some custom software that requires this to be the case and works fine on an older laptops with built-in physical NIC and PCMCIA XIRCOM NIC). The dual NIC laptop communicates with a dual NIC server via a Cisco 2811 router (which has a 16 port switch module at the back) and has vlans set up so.
What I want is for the single NIC laptop (with two virtual NICs) to be able to also communicate with the server. Basically, one NIC is for normal traffic and one is for multicast/broadcast traffic. All three machines need to be able to talk to each other using the NIC for normal traffic and both laptops must be able to receive broadcasts from the server. What is the best way to configure the router to handle the trunking/tagging? Most configuration documentation I read has two complete subnets for the two virtual NICs. Note that all three machines use static IPs and are part of a workgroup so no DNS and domain servers etc.
I am slowly working my way though the setup and configuration of our new 4900m switch. The switch will have a pretty basic operational configuration. We are simply going to network 3 servers together through the swtich. Anyhow, I have been fallowing the guide at this site: [URL]
Basically the switch is brand new and I just setup things such as the clock, the banner, and the hostname. Anyhow, at various points in the guide such as the configuration of the telnet password and especially the interface gigabitethernet I get the "invalid input detected at '^' marker". I also did a show interfaces and noticed there was not any gigabitethernet interfaces but there was a
"FastEthernet1 is down, line protocol is down Hardware is Fast Ethernet for out of band management, address i"
Anyhow, my thinking is continuing on with the guide and at least try to setup the interface for the management port so I can then use the cisco network assistant gui to then configure the rest of the switch.

I've recently purchased a Cisco catalyst 2960S-24TS-L & setup 3 V LANS 10 (no current IP),20 (192.168.2.1) and 30 (192.168.3.1) to reflect the router V LAN configuration & ip information. When connecting my PC to the switch to test connectivity on (2.1 & 3.1) I'm unable to connect to the the net but can successfully ping GW (int FE0.20 & FE0.30) 192.168.2.1 & 3.1.
The router is an Cisco 1801 & it seems this is where the configuration issue is but I'm unable to figure out how to complete the setup. It has been quite awhile since I've configured a Cisco router.
Ive never had this router connected to a switch so all router switch ports are in the default VLAN1 (192.168.1.2), with FE0 disabled. In trying to get the switch to communicate with the router I made the following router config modifications.
FE0 enabled with subinterfaces configured
FE0.10-currently no ip
FE0.20-192.168.2.1/27
FE0.30-192.168.3.1/27
I have two issues I want to resolve:
1) I do not know what additional steps are required to allow 2.1.& 3.1 V LANs to access the net.
2) I want to disable VLAN1 if possible & use the network IP for VLAN10 (192.168.1.0). I'm unsure how to do this as any change on VLAN1 immediately breaks router access and the router reconfiguration becomes more complicated with changes to the FW ACL etc.
I am trying to configure a 3500XL switch (and I know its old). I get to the int fa 0/1 line and thats where it all stops working.
switch#(config-if)#switch port mode access
switch#copy run start
or
switch#(config-if)#switch port mode access
switch#sh run int fa 0/1
It will show the configuration for port fa 0/1 as if I hadn't entered the "switch port mode access" command. Or any other command for that matter. Why the switch is not holding configuration and seemingly loses it as soon as you exit out of each interface?
how to recover password and retrive configuration on Cisco switch 2950 and 3560.I know the way to press and hold the mode button and then plug in the power cord can reset the switch to factory default but it will reset everything to nothing.
