41.1. PoEAC resource

41.1.1. Activating the POEAC resource

Add the resource to the Abilis system with the following command, where n is resource identifier (in the range [1...999]).

[12:25:41] ABILIS_CPX:a res:poeac-1

COMMAND EXECUTED
[Caution]Caution

After adding the POEAC active, you must restart the Abilis to make the resource running (use the command warm start to reboot the Abilis).

[17:14:59] ABILIS_CPX:s p poeac-1 act:yes

COMMAND EXECUTED

[12:59:38] ABILIS_CPX:d p poeac

RES:PoeAc-1 - Not Running, Not Saved (SAVE CONF) ------------------------------
       ------------------------------------------------------------------------
       DESCR:
       LOG:DS             ACT:YES                max-ipres:2    ipres-rxbuf:2  
       ETHRES:NONE                               
       ACNAME:                                   
       EMPTY-EQ-ANY:NO    ALL-SERVICES-OFFER:NO   
       TCP-MSS-CLAMP:YES  TCP-MSS-VALUE:1414

41.1.2. POEAC resource parameters

Use the following command to display the parameters of the resource; the d p poeac ? command shows the meaning of parameters.

[17:25:33] ABILIS_CPX:d p poeac

RES:PoeAc-1 - Not Running, Not Saved (SAVE CONF) ------------------------------
       ------------------------------------------------------------------------
       DESCR:
       LOG:DS             ACT:YES                max-ipres:2    ipres-rxbuf:2  
       ETHRES:NONE                               
       ACNAME:                                   
       EMPTY-EQ-ANY:NO    ALL-SERVICES-OFFER:NO   
       TCP-MSS-CLAMP:YES  TCP-MSS-VALUE:1414

Meaning of the most important parametrs:

LOG

Logging functionalities activation/deactivation.

ACT

Runtime POEAC activation/deactivation.

ETHRES

Lower Ethernet resource [NONE, Eth-XXX, EthUsb-XXX, VEth]

max-ipres

Sets the number of PPPoE sessions the module can support. There can't be more than this amount of external sessions connecting at once.

ipres-rxbuf

Sets the number of PPPoE packets received from client a module can hold while sending other packets to remote PPP.

ACNAME

Access Concentrator name; the name of the Access Concentrator is sent along with responses to hosts. This parameter can be left blank in case there is only one AC in the network for each service-name requested.

EMPTY-EQ-ANY

Select whether the EMPTY service specified in PADI and PADR has to be considered a univocal service (more secure) or ANY service.

ALL-SERVICES-OFFER

Select whether PADO will contain only the requested service (more secure) or the list of all other available services too (less secure).

TCP-MSS-CLAMP

Forces POEAC to change value of Maximum Segment Size in all TCP packets to one equal or lower than set with TCP-MSS-VALUE option to avoid certain problems with PPP over Ethernet “black hole”. Also can be used to reduce link latency at the cost of some bandwidth loss.

TCP-MSS-VALUE

Specifies maximal allowed value for TCP Maximum Segment Size option. This option is only visible if MSS clamping is allowed via TCP-MSS-CLAMP parameter.

VLAN-ID

VLAN Identifier [0, 1..4094, UNTAG] (Only for ETHRES:Eth)

PRIO-PPPOED

PPPOED priority over VLAN [0..7] <Only for VLAN-ID <> UNTAG>

PRIO-LCP-IPCP

LCP and IPCP priority over VLAN [0..7] <Only for VLAN-ID <> UNTAG>

The following command allows the administrator to change the configuration of the resource:

s p poeac-n parameter:value...

[Caution]Caution

To activate the changes made on the upper case parameters, execute the initialization command init res:poeac; while to set act the changes made on the lowercase parameters a save conf and an Abilis restart are required (i.e. with warm start command).
