status link

Displays the status of a single link or all links in the SS7 network.

Syntax

status link n

Option

Description

n

Identifies the link for which you want to obtain status information.

Use an asterisk (*) instead of a number to return status information for all links in the SS7 network.

Returned fields

The returned field names differ, depending on whether you specify a specific link (n) or all links (*). The following table shows both sets of field names where appropriate:

Field

Description

Link

Identifies a link.

MTP3 State
(specific link)

L3 State
(all links)

MTP3 state of the link. Valid values:

Inactive: Link is manually disabled or internally disabled by MTP. The link typically stays inactive until manual intervention.

  • Connecting: MTP is aligning the link.

  • Active: Link is aligned and in service.

  • Failed: Link failed. Typically a transient state until MTP realigns the link.

  • Binding: Link is binding to MTP2. Typically a transient state until the bind succeeds.

  • Unbinding: Link is unbinding from MTP2. Typically a transient state until the unbind succeeds.

  • Unbound: MTP3 has unbound from MTP2 for this link.

MTP2 State
(specific link)

L2 State
(all links)

MTP2 state of locally-terminated links. Valid values:

  • Aligned Ready: Link is aligned at layer two.

  • Aligned Not Ready: Link is aligned at layer two, but a processor outage condition exists.

  • In Service: Link is fully available.

  • Initial Alignment: Attempting to align the link.

  • Out of Service: Received a power on request. Not attempting to align the link.

  • Power Off: Initial state.

  • Processor Outage: Processor outage occurred after being in service.

For remote links, the value of this field is always Remote.

Inhibited (specific link)

Inh (all links)

Indicates whether the link is inhibited. Valid values:

  • None: Link is not inhibited.

  • Local or L: Link is locally inhibited.

  • Remote or R: Link is remotely inhibited.

  • Both: Link is locally and remotely inhibited.

Blocked (specific link)

Blk (all links)

Indicates whether the link is blocked (a local or remote processor outage condition). Valid values:

  • None: Link is not blocked.

  • Local or L: Link is locally blocked.

  • Remote or R: Link is remotely blocked.

  • Both: Link is locally and remotely blocked.

Congested

Indicates whether the link is congested. Valid values:

  • True: Link is congested.

  • False: Link is not congested.

L2 FLow Control Level (specific link)

L2FlowCtlLvl (all links)

For locally-terminated links, flow control imposed by MTP2 due to outbound queue thresholds being reached. Valid values:

  • 0: No flow control

  • 2: Maximum flow control. MTP3 is no longer allowed to send to MTP2.

For remote links, the value of this field is always Remote.

Example

The following example returns status information for link 0:

[ss7cli] > status link 0

MTP3 State            : Active
MTP2 State:           : In Service
Inhibited             : None
Blocked               : None
Congested:            : false

The following example returns status information for all links in the SS7 network:

[ss7cli] > status link *

L2 Flow Control Level: 0
