"network 0.0.0.0"
ahh, one of my favorite topics. I use this all the time (only in my lab, of course). but the "network" statement does two things: 1. If the interface IP falls within the IP range, than participate in the eigrp neighbor process (send out hello's and updates, etc..). this can be stopped by using...- Jsteve

getting switch config via SNMP
This link may point you further in the dirction you are loking for. http://www.routerzone.eu/wiki/index.php/SNMP_MIB_&_OID_Guide,_Cisco One thing I would suggest is to download one of many freeware snmp tools that can pull the config, than sniff the packets to discover the correct MIBs. then... -

High CPU Usage
I have seen the same issues, but on 3750's. I had to change the SDM profile to routing. Once I did and rebooted the CPU dropped to 4% the command I believe is sdm prefer routing http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/12.2_46_se/configuration/guide/swsdm.html -
CCIE R&S Lab Prep
2) Apart from Dynagen what else would I need to prepare? I mean what other Cisco hardware? I dont have a big budget hence am trying to make use of Dynagen as much as possible. this depends on how good you are with the 3560/3550/3750 switches. You will not get the switching section down with...- Jsteve

Cause for high CPU usage?
Burt is right 91% of the CPU usage is traffic being punted to the CPU Normally I have seen all of my traceback errors related to memory leaks triggered by an IOS bug. If it's a memory leak,a switch reload will fix the issues. If a reload does not fix the issue, and if this is a 6500, you can... -
Need multiple non-subnetted IPs on ASA external interface
one more thing. I added an acl that opens everything to your inside servers, but it is best practice to just open the specific services you need. for example, your web server acl would be: access-list acl_outside permit tcp any host 192.168.1.102 eq www instead of: access-list acl_outside... -
Need multiple non-subnetted IPs on ASA external interface
forgot the acl access-list acl_outside permit ip any host 192.168.1.101 access-list acl_outside permit ip any host 192.168.1.102 access-list acl_outside permit ip any host 192.168.1.103 ! access-group acl_outside in interface outside -
Need multiple non-subnetted IPs on ASA external interface
I would suggest looking at the "Cisco Firewall Video Mentor" on the safaribooks online website. You may need to sign up for a 10day free trail, but it is worth the effort and is exactly what you need. when you open up conduits to connect to devices from the outside, it is best practice to use a... -
Need multiple non-subnetted IPs on ASA external interface
5 Ip addressed will fall into a /29 or /28, but you should be configuring the interface for the mask that the IPS gave you, not sure what your really trying to accomplish. I would think that if I got 5 IPs from my ISP, i would just configure 1 ip connecting to the ISP and use the other 4 for... -
How To Enable Multicast in a Campus Network
1) I would get ride of the sparse-dense-mode and just change it to sparse-mode. Also add the pim sparse-mode to the loopback on your core switch. 2) verify that the tunnel interfaces are pim-neighbors with the "show ip pim neighbors". If they are not, you need to look at the pix for further... -
OSPF Peering across multiple VLANs
Most likely you are peering each vlan across a trunk link, which is not necessary. Only one peer is needed. You can eliminate some of the peering by adding "passive-interface" for the "Stub" vlan LAN segments. It really depends on what each vlan is used for in your network, like most of the guys... -
Boot from Sup720 flash card in Cat6500
Are you running the new sup720 VSS modules? they ussually ship with the "Modular IOS" code, which is the one loading. you can tell by the v in wan-vz, the new VSS modules can only run the Modular codes, so most likely your mz code trys to boot but is failing. Once the image is installed, all... -
Preparing for CCIE (best way/strategy)
NP here is a quick tcl ping script that is easy to remember. enter the shell: tclsh cut and paste script: foreach ip { 1.1.1.1 2.2.2.2 3.3.3.3 4.4.4.4 5.5.5.5 6.6.6.6 } {ping $ip} to exit out of the shell: tclq- Jsteve
