How To Restart CUCM Web Interface


بسم الله والحمد لله والصلاة والسلام علي رسول الله وآله وصحبه وإخوانه وسلم

How To Restart CUCM  Web Interface

To do this you need to restart the Cisco Tomcat service, but first what is Tomcat service:

Apache Tomcat (or simply Tomcat) is an open source web server and servlet container developed by the Apache Software Foundation (ASF). Tomcat implements the Java Servlet and the JavaServer Pages (JSP) specifications from Sun Microsystems, and provides a "pure Java" HTTP web server environment for Java code to run.

To display services running on the CUCM:
admin: utils service list

To restart the Tomcat service or simply start it if it is stopped:
admin: utils service restart Cisco Tomcat

What Is The Difference Between TFTP Option 150 and TFTP Option 66?


بسم الله والحمد لله والصلاة والسلام علي رسول الله وآله وصحبه وإخوانه وسلم

What Is The Difference Between TFTP Option 150 and TFTP Option 66?

- DHCP Option 150 is Cisco proprietary. The IEEE standard that matches with this requirement is Option 66. Like option 150, option 66 is used to specify the Name of the TFTP server.

- Option 66 is an open standard juniper supports it. RFC 2132 defines option 66.

- DHCP option 150 supports a list of TFTP servers (Multiple Server IPs).

- DHCP option 66 only supports the IP address or the hostname of a single TFTP server. 

For some third-party SIP phones, it may be necessary to specify Option 66 (the TFTP server DNS name).

How To Manage Access To Cisco Devices Based On Active Directory Authentication


بسم الله والحمد لله والصلاة والسلام علي رسول الله وآله وصحبه وإخوانه وسلم

How To Manage Access To Cisco Devices Based On Active Directory Authentication

If you have many levels of administrators in your network and you want to give them different privileges, doing so using the local database on Cisco devices is not the optimal, you can grant them access based on the authentication against active directory database where the user will login to the device using his normal user name and password then he will be granted the privilege level that you assigned to his or her group.Note that this lab is done using GNS3 and Windows server 2008 R2.

 

The commands used on Cisco router:

aaa new-model
!
aaa group server radius IAS
 server 192.168.1.50 auth-port 1812 acct-port 1813
!
aaa authentication login userAuthentication local group IAS
aaa authorization exec userAuthorization local group IAS if-authenticated
aaa authorization network userAuthorization local group IAS
aaa accounting exec default start-stop group IAS
aaa accounting system default start-stop group IAS
!
aaa session-id common
radius-server host 192.168.1.50 auth-port 1645 acct-port 1646 key cisco
radius-server host 192.168.1.50 auth-port 1812 acct-port 1813 key cisco
!
privilege exec level 1 show config
privilege exec level 1 show ip interface brief
!
ip radius source-interface fa0/0
!
line vty 0 4
 authorization exec userAuthorization
 login authentication userAuthentication
 transport input ssh telnet
!
line vty 5 15
 authorization exec userAuthorization
 login authentication userAuthentication
 transport input ssh telnet
