Error encountered: An unknown error occurred while accessing the upgrade file

If you get an error ( Error encountered: An unknown error occurred while accessing the upgrade file ) while upgrading you might want to check the install log file for "ntp" and see if you have this error in the log. You must have an external NTP server before the upgrade will complete. * Note* this upgrade was on a vmare,CUCM 7.x to 8.x upgrade.

CUCM 7.x NTP server won't sync

No matter what external NTP server I setup it wouldn't sync since the stratum was 16 on all of them. Not sure what was blocking this but once I changed the NTP server to the 2811 voice interface it synced properly. So if you do this make sure the 2811 has the correct time.

Dell 6224 multiple vlans with vlan 1 routing command

You must change the management vlan to something other than vlan 1 if you want to turn on vlan 1 routing.

-To change mng vlan get in config mode then,
(config)# ip add 192.168.254.1 255.255.255.0
ip address vlan 254

-After that you can give vlan 1 ip address and add the routing command to it.

Cisco ASA , 2nd vlan can't get to internet

This is a reminder to those who have multiple vlans and an ASA. You have to add the command "route LAN 10.10.10.0 255.255.255.0 10.10.20.254" to route traffic form vlan 2 10.10.10.0 to vlan 1 10.10.20.254.

- Until this command was entered vlan2 could access things on vlan 1 but coudn't get to the internet.

Setting up guest access on WAP4410N

- Configure both SSIDs in the wap admin page.
- Turn on vlans , configure guest access for vlan 2 (or whatever you what).
- On ssg5(firewall) configure a SubInterface bgroup0.2 and assign vlan 2.
- Put bgroup0.2 in the DMZ.
- Configure dhcp on the DMZ.
- Add policy from DMZ to Untrust (any to any) , make sure to go to advanced under policy and check source NAT or you won't be able to get online from vlan 2.
- At this point you can connect to the guest SSID and you should get ip in DMZ (vlan 2). Also, test to make sure you can only get on internet not the main network.

fax h323 gateway didn't work until fax protocol pass-through

This is an example of a dial-peer I made to make faxes work on a FAx server at a Main site. Until this command was added the faxes would time out.

command to have caller-id name for incoming calls

I had a H323 gateway and cisoco Callmanager. The caller-id name wasn't working on incoming calls until I added this command on the serial interface for the PRI "isdn supp-service name calling".

Example:
interface Serial0/0/1:23
no ip address
encapsulation hdlc
isdn switch-type primary-ni
isdn incoming-voice voice
isdn supp-service name calling
no cdp enable
