3. DSL Card Configuration
3-18
April 2001 8000-A2-GB26-50
Table 3-3. Interfaces Options
General (General Interfaces) A-C-A
Provides the capability of configuring and viewing basic card interface information about a
given interface, including binding filters.
Interface Name
– eth1:1 = Ethernet network interface; sar1:1 = ATM network interface;
dsl1:1 through dsl4:1 = 4-port DSL card interface; dsl1:1 through dsl12:1 = 12-port DSL
card interface, dsl1:1 through dsl24:1 = 24-port DSL card interface.
Type
– Static or Dynamic interface type.
Protocol
– Interface protocol: Ether (for Ethernet interface), MPOA (for ATM network
interface), E_HDLC, or FUNI.
MTU
(max)
– 64–1600 bytes (Default = 1536). Receipt of packets above the MTU setting
will be dropped.
NOTE: The above MTU values are the only values you may enter. Make certain that if
you change from the default value, the new numbers are appropriate to your network.
Do a card reset or reset the Ethernet interface.
Inbound Filter Name
–
Enter the filter name with a maximum of 12 characters. This field
appears only if the DSL interface is selected. To view a list of configured inbound filters,
press Ctrl-v.
NOTE: An inbound filter acts on packets in the upstream direction from the client to
the NSP server.
Outbound Filter Name
–
Enter the filter name with a maximum of 12 characters. This
field appears only if the DSL interface is selected. To view a list of configured outbound
filters, press Ctrl-v.
NOTE: An outbound filter acts on packets in the downstream direction from the NSP
server to the client.
Control (Control Interfaces) A-C-B
Gives the user the ability to start, stop (disable), and monitor (up, down, or testing) the
current state of an interface.
NOTE: Stopping the interface disables all of the traffic on that port, including
diagnostics. If you want to disable only customer traffic, disable all VNIDs on that port.
There are no user-configurable elements on this screen except for the ability to start and
stop the interface. Valid choices for the DSL card are eth1:1 = Ethernet network interface;
sar1:1 = ATM network interface; dsl1:1 through dsl4:1 = 4-port DSL card interface; dsl1:1
through dsl12:1 = 12-port DSL card interface, dsl1:1 through dsl24:1 = 24-port DSL card
interface.
On the NMS side, when a DSL card first comes up, all its ports are administratively down.
Once connected, a port becomes active. Then if a port goes down, it is operationally
down. You must use this Control option to bring the port administratively down (X appears
