Table 6.3: CLI Display of POS Interface Information
Displays...
The chassis slot and port number of the interface.
The state of the link, which can be one of the following:
• down
• up
The encapsulation type in use on the interface. The encapsulation
type can be one of the following:
• hdlc – High-Level Data Link Control
• ppp – Point-to-Point Protocol. This is the default.
To change this parameter, see "Changing the Encapsulation Type" on
page 6-6.
The clock source, which can be one of the following:
• int – The interface is using the clock on the POS module.
• line – The interface is using the clock source supplied on the
network.
To change this parameter, see "Changing the Clock Source" on
page 6-6.
The loopback state of the interface. The loopback state can be one of
the following:
• int – The loopback path consists only of the POS circuitry on this
interface.
• line – The loopback path consists of both this POS interface and
the POS interface at the remote end of the link.
• none – The interface is not operating in loopback mode.
To change this parameter, see "Changing the Loopback Path" on
page 6-7.
The bandwidth of the interface, which can be one of the following:
• 155
• 622
• 2488
To change this parameter on the B2P622 module, see "Changing the
Bandwidth" on page 6-8.
The Maximum Transmission Unit (MTU) of packets sent on this
interface. The MTU can be from 60 – 4770 bytes. The default is 4470
bytes.
To change this parameter, see "Changing the Bandwidth" on page 6-
8.
