The second parameter that you must specify to allow the EMS Server to recognize this BTS is a
community string for the EMSs Simple Network Management Protocol (SNMP) interface. The
default community string shipped with the BTS is “public”. Press the Enter key to accept this
default, or type in a new value and press the Enter key to alter it:
snmp community : public
Traffic Path
The last major block of configurations required for an Ethernet backhaul to the BTS is the traffic
path parameters. The first prompt instructs the BTS to use the Ethernet as the WAN (backhaul)
configuration. It must be set to “enet” for an Ethernet backhaul.
If “atm” is selected, proceed with the description in the ATM or IMA sections. The BTS is pre-
configured to use Ethernet for the WAN connection. Press the Enter key to accept this default:
traffic path : enet [enet|atm]
The BTS address is specified next. Every BTS must be uniquely addressed and have values that
equate in the EMS configurations. This address information defines the Layer 2 parameters first,
and then it defines the Layer 3 parameters. For Layer 2, you are only given an opportunity to see
the Ethernet Media Access Control (MAC) address used by this BTS. This is a unique number
programmed in the BTS. You cannot alter it. However, situations may develop in which you
need to know the MAC address and, therefore, need to display the information. For example:
mac address : 00:04:6a:00:01:20
Next are the IP addresses that represent this BTS: one for the active CC card and one for the
standby CC card. Enter the IP for the active controller card, for 172.16.23.181, and the next IP
(172.16.23.182
) is automatically assigned to the Standby card.
ip on enet (active) : 172.16.23.181
ip on enet (standby) : 172.16.23.182
The standby field is only displayed for your convenience and cannot be altered. Note that the
BTS automatically handles switching the address when a failure occurs on an active Controller
card, requiring the standby Controller to go into service. However, the MAC addresses remain
fixed.
Coupled with any IP configuration is a need to specify the corresponding subnet mask. Refer to
common network administration literature for guides on addresses, networks, masks, and
gateways. In short, the subnet mask identifies the portion of the IP address that is common to
those devices connected to the same Ethernet. The most important “other” device is the BTSs
