Which interfaces of the AR router support PPPoE dialup

The number of PPPoE sessions supported by AR models is as follows: - AR120&AR150&AR160&AR200&AR500, AR1200, AR2201-48FE, AR2202-48FE, and AR2204: 128 - AR510: 4 - AR2220E, AR2220L, and AR2220: 512 - AR2240 and AR3260: SRU40 and SRU60: 512 SRU80: 1024 SRU100 and SRU200: 6144 - AR3670 (SRUX5): 6144

MPLS can be configured on the following interfaces: - GE interface - GE sub-interface - XGE interface (V200R005C10 and later versions) - XGE sub-interface (V200R005C10 and later versions) - Ethernet interface - Ethernet sub-interface - Eth-Trunk - Eth-trunk sub-interface - Serial interface - POS interface - MP-Group - IP-Trunk (V200R005C10 and later versions)

For V200R002C00 and later versions, only Layer 2 Ethernet interfaces on the AR series router support LLDP. For V200R002C01 and later versions, Layer 2 and Layer 3 Ethernet interfaces on the AR series router support LLDP.

When the AR router functions as the PPPoE or PPPoEoA client, it continuously sends connection requests to the PPPoE or PPPoEoA server. When the maximum number of connection attempts is reached during the quiet period, the PPPoE or PPPoEoA server does not receive requests from the client. The PPPoE or PPPoEoA server receives connection requests only after the quiet period is exceeded. During the quiet period, the client repeatedly sends connection requests to the PPPoE or PPPoEoA server, wasting resources. The quiet period and retransmission count during the silent period can be configured to solve this problem. When the retransmission count is exceeded during the quiet period, the client stops sending connection requests.

The PPPoE client cannot be configured on a VLANIF interface, but the PPPoE server can be configured on the VLANIF interface.
