Cisco 10000 Series Router Quality of Service Configuration Guide
16-18
Configure the following commands and recommended values on the virtual template interface:
ppp max-configure 110
–
ppp max-failure 100
–
ppp timeout retry 5
–
keepalive 30
–
Configure the hold-queue command in interface configuration mode for all physical interfaces,
except when configuring the ATM OC-12 line card. The OC-12 does not require the hold-queue
command.
Single-VC MLP over ATM member links are restricted to non-aggregated PVCs (for example,
variable bit rate-nonreal-time (VBR-nrt) and constant bit rate (CBR) ATM traffic classes only).
The multilink interface can have only one PPP link that is between 64 and 2048 kbps. The router
supports a maximum of one member link per bundle.
The router supports a maximum of 8192 bundles per system and a maximum of 8192 member links
per system.
The valid multilink interface values are 10,000 and higher.
Interleaving occurs on one member link.
MLP VCs cannot be on-demand VCs that are automatically provisioned.
Associating MLP over ATM VCs with ATM virtual paths (VPs) is discouraged, though not
prevented.
Cisco IOS software supports a maximum of 4096 total virtual template interfaces.
We strongly recommend that you use only strict priority queues when configuring MLP over
ATM-based LFI. For more information, see

4-Port OC-3/STM-1 ATM
1-Port OC-12 ATM
