The second one consists of agian Cyberoam UTM 1000i with Bluecoat Packetshaper.Packetshaper is a Bandwidh Management solution used to control the bandwidth for the users.
The third project which is going to come is regarding a second bandwidth management solution from Allot. The product is Netenforcer.You can get more info on http://allot.com ]]>http://nityasworld.com/index.php?entry=entry100513-1249332010-05-13T00:00:00Z2010-05-13T00:00:00ZView of Dabhol from river

Cisco Physical Security Solution and Unified Communications
Last week we were present at Cisco stall for demonstrating UC and Physical Security Solution of Cisco at the Command Conference.The event was for the army signals officers.
Cisco Physical Security products offer video-surveillance and access-control solutions that are easy to integrate with existing physical security infrastructure.
# Cisco Physical Access Control # Cisco Video Surveillance IP Camera # Cisco Hybrid Analog and Network Video Surveillance products # Cisco Network-Centric Video Surveillance products The more info can be found at below cisco link http://www.cisco.com/web/solutions/ps/products.html
For Unified Communication we showcased Cisco MCS Media Convergence Server and Unity express products. The phones we kept were Cisco 7965 and 7975 For MCS overview please visit this cisco page http://www.cisco.com/en/US/products/hw/ ... index.html Unity Express allows you to integrate your mailing solution so as if the call gets missed the caller can send it as Voicemail. Please visit the URL for UNity express overview http://www.cisco.com/en/US/products/sw/ ... index.html

OSPF Notes Part 5
OSPF Network Topology Options OSPF assumes a subnet is broadcast-capable by default. OSPF Network Types Broadcast multiaccess Point-to-point Point-to-multipoint broadcast Point-to-multipoint nonbroadcast Nonbroadcast multiaccess (NBMA)
NBMA and point-to-multipoint are standards-compliant (RFC 2328), whereas point-to-multipoint nonbroadcast, broadcast, and point-to-point implementations are Cisco proprietary. NBMA networks utilize DRs like broadcast networks, however neighbors must be manually defined instead of being automatically discovered.

OSPF Notes Part 4
OSPF cost can be manually specified per interface: Router(config-if)#ip ospf cost <cost>
An alternative to defining static costs per interface is to change the numerator bandwidth (default 100Mbps): Router(config-router)ospf auto-cost reference-bandwidth <reference speed>
Reference speed is a 32-bit value (1 - 4294967). If reference speed is modified, the same modification should be performed on all routers within the area.
Router Priority Default DR election priority is 1, and a router with a priority of 0 will not become a DR. Priority range is 0 - 255.
Router(config-if)#ip opsf priority <priority>
Verifying OSPF Configuration show ip ospf - OSPF process details
show ip ospf database - Contents of the topology database
show ip ospf interface - Interfaces participating in OSPF
show ip ospf neighbor - Neighbor information
show ip protocols - Displays all active routing protocols

OSPF Notes Part 3
Packet Types OSPF is IP protocol 89. Hello - Used to establish communication with directly connected neighbors Database Descriptor (DBD) - Lists router IDs from which the router has an LSA and its current sequence number Link State Request (LSR) - Request for an LSA Link State Update (LSU) - Reply to an LSR with the requested information Link State Acknowledgment (LSAck) - Used to confirm receipt of link-state information
Packet Fields Version - Version of OSPF being run Type Length Router ID Area ID Checksum Authentication type (none/plaintext/md5) Authentication data Data Configuring OSPF in a Single Area Necessary information: OSPF process ID (locally significant) Participating interfaces Area ID Router ID Enable OSPF Router(config-router)# router ospf <process number>
Configure Included Networks Router(config-router)# network <network> <wildcard mask> area <area ID>
A single interface can be specified by supplying its IP address and a null wildcard mask: network 192.168.0.1 0.0.0.0 area 0
Router ID If no router ID has been administratively declared, a router will choose the highest loopback IP address. If no loopback addresses are present, the highest IP address of the first active interface will be used.
A router ID can be manually specified: Router(config-router)# router-id <IP address>
Best practice dictates the creation of a loopback address to be used as the router ID for stability and continuity: Router(config)# interface loopback 0 Router(config-if)# ip address <IP address> <subnet mask>
Default Cost Link cost is a 16-bit value (0-65535); default cost is calculated as 100Mbps/interface bandwidth.(Interfaces 100Mbps and faster are assigned a cost of 1.)
