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
!

Class Of Restriction (COR) Superset Or Subset


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

Class Of Restriction (COR) Superset Or Subset

Keep in mind the following rule:
- for a call to be successful the incoming COR must be a superset or equal to the outgoing COR.
- to deny a call the incoming COR must be a subset of the outgoing COR.


Lab Time:

 
Example 1 : Call fail ( the incoming COR is a subset of the outgoing COR)
R1:
dial-peer cor custom
name sales
name accounting
name laboratory
!
dial-peer cor list sales-out
member sales
member accounting
member laboratory
!
dial-peer cor list sales-in
member sales
member accounting
!
ephone-dn 1
cor incoming sales-in
!
dial-peer voice 1 voip
cor outgoing sales-out

Result: 



Example 2 : Call Success (the incoming COR is equal to the outgoing COR)
R1:
dial-peer cor custom
name sales
name accounting
name laboratory
!
dial-peer cor list sales-out
member sales
member accounting
member laboratory
!
dial-peer cor list sales-in
member sales
member accounting
member laboratory
!
ephone-dn 1
cor incoming sales-in
!
dial-peer voice 1 voip
cor outgoing sales-out

Class Of Restriction (COR) Lab Using GNS3


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

Class Of Restriction (COR) Lab Using GNS3

- First Keep in mind the following:

Each dial-peer or phone-dn can have one incoming COR list and one outgoing COR list:
- Incoming COR list means: the dial-peer or the phone can initiate calls or not.
- outgoing COR list means: who can call this dial-peer or phone or not.
- If no incoming COR list: this means that the dial-peer or the phone can call any one. Regardless of the outgoing COR setting on the phone called
- if no outgoing COR list: this means that anyone can call this dial-peer or phone regardless if the phone calling has an incoming COR set or not.
- If the incoming COR list is a superset or equal to the outgoing COR list this means that the call will succeed.
- If the incoming COR list is not a superset or equal to the outgoing COR list this means that the call will fail.
- When you begin configuration first you need to configure the outgoing COR.
- To deny a call when you configure the outgoing COR make sure that it is a superset of the incoming COR.
   Now it is Lab time:
 - The Manager can call the Employee but the Employee can not. Also the Employee should call any other dial-peer.
dial-peer cor custom
name employee
name manager
!
dial-peer cor list Manager
member manager
!
dial-peer cor list Employee
member employee
!
ephone-dn 1
cor outgoing Manager
!
ephone-dn 2
cor incoming Employee

H3C And HP Networking

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

H3C And HP  Networking

H3C was initially a joint venture agreement between 3Com and Huawei.
They set up a company called H3C which had a majority control to Huawei however in the agreement 3Com could buy a controlling share a few years later.
In 2007 3Com bought over H3C completely and as such it became an arm of 3Com.
H3C is massive is China and sells enterprise gear which is meant to compete with Cisco.
The interface which the H3C devices use is very similar to the CLI to Cisco with differences in some commands.
By the way All huawei datacom devices use the same os called vrp (versatile Routing Platform) which is very similar to H3C's OS (Comware).
All equipment was rebranded as H3C at this point and as such 3Com on network devices disappeared.
On April 12, 2010, Hewlett-Packard (HP) completed the acquisition of 3Com and the 3Com brand has been disappered all together with a new HP brand covering all the network gear.
However H3C will remain the brand in China as it is a massive brand over there and they don't want to risk losing the market due to a brand name change.

H3C’s O/S, Comware 5 is similar to IOS in its structure and command set, it is not “copied IOS”.
Comware 5 was written from scratch (a complete rewrite from Comware 3).
The drivers are of course different on the various products, but all the features exist in the code on every product,
and Comware 5 does not use a feature set model to unlock them.

The HP ProVision operating system (which is very similar to Cisco's IOS) runs on HP 3500, 5400zl, 6200yl, 6600, and 8200zl Switch Series.
Other HP switches use an operating system that is very similar to the ProVision operating system.

But why am i writing this post today?
as you know my main concern in IT study is: does the vendor has a simulator (emulator will better) or no? because this which makes me continue in the study.
Huwaei and 3COM has a simulator for H3C prouducts which HP now provides this simulator to their partners only. it based on Comware 5:
[H3C] display ver
H3C Comware Platform Software
Comware Software, Version 5.20, Release 9101
Copyright (c) 2004-2010 Hangzhou H3C Tech. Co., Ltd. All rights reserved.
SIMWARE uptime is 0 week, 0 day, 0 hour, 0 minute

This if you are in the situation where you have  HP network project and you have to study for it, it is now available.

I hope that has been informative to you.

How to Simulate PSTN Using GNS3


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

How to Simulate PSTN Using GNS3

 

This is my initial CCNA VOICE lab using GNS3. The most important in this post is how to simulate the Public Switched Telephone Network (PSTN). As you know currently GNS3 does not support FXS or FXO ports, so the following configuration showing you how to get around this by Allah’s willing.
So, I have used the following IOS:
(C3745-IPVOICE_IVS-M), Version 12.4(15)T14
It is the same on all routers and the PSTN, this is to decrease the processor load. Because as you know GNS3 uses the ghost image feature which uses a single IOS on all routers from the same type instead of using a dedicated image for each router.
