Cisco Cisco Aironet 340 Ethernet Bridges Guia Do Utilizador

n If protocol filtering is enabled then the appropriate parts of the 

packet will be examined.

The Aironet 340 Series Bridge can attach directly to 10Base2 (Thinnet), 
10Base5 (Thicknet) or 10BaseT (Twisted Pair) Ethernet LAN segments. 
These segments must conform to IEEE 802.3 or Ethernet Blue Book 
specifications.

If the existing infrastructure to which the bridge is to be attached is not 
Ethernet-based, an Ethernet segment can be added by installing an 
Ethernet Network Interface Card (NIC) in the File Server or by adding a 
third-party bridge.

The bridge appears as an Ethernet node and performs a routing function 
by moving packets from the wired LAN to remote workstations (per-
sonal computers, laptops and hand held computing devices) on the Wire-
less Infrastructure. 

Protocols supported:
n TCP/IP based protocol products

n SNMP Protocol – The resident agent is compliant with the MIB-I 

and MIB-II standards, TCP/IP based internets, as well as a custom 
MIB for specialized control of the system.

The Aironet 340 Series Bridge uses a radio modulation technique known 
as Direct Sequence Spread Spectrum transmission (DSSS). It combines 
high data throughput with excellent immunity to interference. The 
bridge operates in the 2.4 GHz license-free Industrial Scientific and 
Medical (ISM) band. Data is transmitted over a half-duplex radio chan-
nel operating at up to 11 Megabits per second (Mbps).
