Network devises

 At 4 HandyCom we use different network devises for infrastructure, which we catalogue by devise, brand and model: 

Devises	Brand	Model
Router	Mikrotik	RB2011UiAS-2HND-IN RB1100AHx2 CCR-1009-8g15
Switch (Capa 2 y 3)	Extreme	X440G2-12p-10G4 X440G2-24p-10G4 X440G2-48p-10G4 Extreme 220-Series 24GE PoE+ Extreme 220-Series 48GE PoE+
Switch Core	Extreme	VSP series 8000
IP Phone	Grandstream Cisco Polycom Yealink	Grandstream Modelos GXP21XX Cisco Modelos SPA-500 Polycom Modelos VVX Yealink Modelos T40 y W50
Access Point	Extreme Ruckus Xirrus	Extreme Wing ATOM

Differences

Each devise previously mentioned has a specific function that characterizes and differentiates each other, the following table will list their main characteristics.

Equipos	Functionality	OSI Model Layer
Router	IP adress routing ACL management Dynamic and static routing protocols DHCP Server Firewall functionality	Layer 3
Switch	Data link Packet flow controll Grouping of MACs Connections between networks VLANs	Layer 2
Switch Core	Layer 2 and 3 functionality Dynamic and static routing protocols VRFs usage  ACL management High CPU performance VLANs	Layer 2 y 3
IP Phone	VoIP functionality Packet handling over the network	Layer 2
Access Point	WI-FI delivery using the ac/ b/g/n standards 2.4 GHz and 5GHz band handling  SSIDs	Layer 2

Uses

Within the implementation these teams can help us solve and / or adapt the requests that customers require, as an example shown in Figure 1.0,  where the example of the implementation and use of network equipment is given.

Figure 1.0 Network topology

As shown in the previous topology, each Network Equipment has a specific use. The main uses of each devise are listed below.

Router:

• It's main use IP adress routing
  
• Interconnection of internet links
• Network monitoring
• Policy creation
• NAT
• DHCP server
• VPNs

Switch:

• LAN equipment connection
• Provide equipment with power through PoE technology
• Packet flow control
• DHCP server
• VLANs

Switch Core:

• VRF creations
• Dynamic and static routing
• VLANs
• Packet flow control
• Connection between LAN and WAN equipment

IP Phone:

•  VoIP telephony

Access Point:

• ACL management
• WI-FI delivery using the ac/ b/g/n standards
• 2.4 GHz and 5GHz band handling 
• SSIDs
