Step Command Remarks
15. Shut down the POS interface. shutdown
Optional.
By default, a POS interface is
enabled.
NOTE:
•
The POS interface can work in the master clock mode only when the SRPU (or the main control board)
is installed with a clock daughter card.
• IPv6CP of PPP cannot get the peer IPv6 address through auto negotiation. Therefore, when a POS
interface is used for IPv6 hardware forwarding, you need to configure static routes or routing protocols
on it.
• If no cable is connected to a physical interface, shut down the interface with the shutdown command to
prevent anomalies caused by interference. Use the shutdown command with caution, because once an
interface is shut down, it stops operating.
• You cannot add a POS interface to an MP group, so you cannot configure the ppp mp { mp-group
mp-number | short-sequence } command on a POS interface.
Switching interface type between POS and Layer 3 GE
On sub-card PIC-TCP8L, you can switch the interface type of a POS interface to Layer 3 Gigabit Ethernet
(GE) and vice versa to adapt to different circumstances.
To switch the type of an interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
• Enter POS interface view:
interface pos
interface-number
• Enter Layer-3 GE interface
view:
interface GigabitEthernet
interface-number
Use either command.
In POS interface view you can switch the
type of the interface from POS to Layer-3
GE, and in Layer-3 GE interface view
from Layer-3 GE to POS.
3. Switch the interface type. port-type switch interface-type N/A
Displaying and maintaining POS interfaces
Task Command Remarks
