Performance and Scalability for Single-VC MLP Over ATM-Based LFI
The following list describes how to enhance performance and scalability for Single-VC MLP over
ATM-based LFI:
• 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.
For more information, see the “Scalability and Performance” chapter in the Cisco 10000 Series Router
Broadband Aggregation, Leased-Line, and MPLS Configuration Guide.
Restrictions and Limitations for Single-VC MLP Over ATM-Based LFI
• 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
Chapter 8, “Prioritizing Services.”
Line Card Support for MLP Over ATM-Based LFI
The following line cards support MLP over ATM-based LFI for the Cisco 10000 series router:
• 8-Port E3/DS3 ATM
• 4-Port OC-3/STM-1 ATM
• 1-Port OC-12 ATM
