Configuring HSRP

How to use Hot Standby Router Protocol (HSRP) on the Catalyst 3750X switch to provide routing redundancy for routing IP traffic not dependent on the availability of any single router. HSRP for IPv4 is supported on switches running the IP base or IP services image. To use HSRP for IPv6, see Chapter 39, "Configuring IPv6 Unicast Routing."

Routers in an HSRP group can be any router interface that supports HSRP, including Catalyst 3750 routed ports and switch virtual interfaces (SVIs).

When a device is participating in an HSRP standby routing and clustering is enabled, you can use the same standby group for command switch redundancy and HSRP redundancy. Use the cluster standby-group HSRP-group-name [routing-redundancy] global configuration command to enable the same HSRP standby group to be used for command switch and routing redundancy. If you create a cluster with the same HSRP standby group name without entering the routing-redundancy keyword, HSRP standby routing is disabled for the group.

This example shows how to bind standby group my_hsrp to the cluster and enable the same HSRP group to be used for command switch redundancy and router redundancy. The command can only be executed on the cluster command switch. If the standby group name or number does not exist, or if the switch is a cluster member switch, an error message appears.

 Switch# configure terminal
 Switch(config)# cluster standby-group my_hsrp routing-redundancy

 Switch(config)# end

How to Save a Cisco 3560 Switch Configuration

Cisco Catalyst switches can be configured using a number of different utilities. The most common way to configure a Cisco Catalyst switch, such as the Catalyst WS-C3560X-24T-L , is using the command line interface (CLI) provided with the switch. When typing configuration commands into the switch, all configurations are held in active memory on the switch, but are not saved to the startup configuration until the command to save the configuration to flash is issued.  

Instructions
1 Click the Windows icon in the lower left corner of the desktop, then click “Programs” and click “Accessories.” Right-click the command line icon in the menu that appears, and then click “Run as Administrator.” The command line window will appear.

2 Type “telnet x.x.x.x” on the command prompt, replacing the “x.x.x.x” with the IP address of the Cisco Catalyst 3560 switch, and then press "Enter.”

3 Type the telnet access password when requested on the command prompt and press “Enter.”

4 Type “enable” on the command line and press “Enter.” Type the Privileged Exec password on the command prompt when requested and press “Enter.”

5 Type “write memory” on the command line and press "Enter.” The running configuration stored in the switch memory has now been saved to the startup configuration in the flash memory of the Cisco Catalyst WS-C3560X-24T-S   switch.

Cisco 2801 + WIC-1T problem

I've got a problem with my new 2801 router and HWIC-1T   card. My connection to Internet is 2Mbit/s sync HDSL by modem Schmidt with V.35 interface.
Everything works fine with old Cisco 2610 router + WIC-1T, but when putting the same WIC-1T to any slot of 2801 there is no link... Serial interface is detected and up, line protocol is up, but it is still not responding.

Configuration both of routers is the same, no changes with default clock rates or something... I've tested two different WIC-1T cards and there was the same behaviour, 2610 works fine, 2801 not...

Here is my config, sh ver, debug and all that can be helpful in diagnose.

I've compared both releases and there should be no problem with 12.4, it has all of the 12.3T funcionality  WS-X45-SUP7L-E   and much more. With RAM there will be no problem, my 2801 has got 256MB while there's requirement of 128 megs.
