Can AR1220 support 100 users

39

As described on brochures, AR1220 can support 100 users if the traffic of each user is not large. However, the performance of AR1220 may decrease if the traffic of each user is large.
Recommended user numbers of different devices are described as follows:
AR3260: more than 350 users
AR2220: 50 to 350 users
AR1200: fewer than 50 users
AR150 and AR200: fewer than 30 users

How does an AR limit intranet users to access the network
An AR can be configured with a traffic policy to limit intranet users to access the network.
If an intranet user uses the static IP address, a traffic policy can be configured to deny the intranet user. If a terminal device obtains an IP address using DHCP, the IP address of the terminal device that is limited to access the network needs to be determined.
This prevents the impact on other users' Internet access after the address is released and allocated to other terminals.
The configuration roadmap is as follows:
Create an ACL and configure rules that match the IP or MAC addresses of users who are limited to access the network (ensure that users are connected to the router directly or through a switch). For example:
Create an ACL based on IP addresses.
[Huawei] acl 3000  //Create ACL 3000
[Huawei-acl-adv-3000] rule permit ip source 10.1.1.1 0.0.0.0   //Match terminal 10.1.1.1 of the intranet.
[Huawei-acl-adv-3000] rule permit ip source 10.1.1.2 0.0.0.0  //Match terminal 10.1.1.2 of the intranet.
Create a traffic classifier that matches acl 3000.
[Huawei] traffic classifier c1
[Huawei-classifier-c1] if-match acl 3000
Create a traffic behavior to limit the matched IP address to access the network.
[Huawei] traffic behavior b1
[Huawei-behavior-b1] deny 
Create a traffic policy and bind the traffic classifier and traffic behavior to the traffic policy.
[Huawei] traffic policy test 
[Huawei-trafficpolicy-test] classifier c1 behavior b1
Apply the traffic policy test to the interface.
[Huawei] interface GigabitEthernet 0/0/1
[Huawei-GigabitEthernet0/0/1] traffic-policy test inbound 
Using the same method to match source MAC addresses except for creating an ACL. For example, permit users with the intranet MAC address 1122-1122-1122 to access the network.
[Huawei] acl 4000 //The Layer 2 ACL number must be in the range 4000 to 4999.
[Huawei-acl-L2-4000] rule permit source-mac 1122-1122-1122
Use the preceding profile to perform other configurations.

Can an AR prevent users from accessing websites
AR150&160&200&1200 and AR2200 (AR2201 and AR2202) series routers do not support deep security defense, which means URL filtering is not supported. URL filtering can only be applied to HTTP URLs.

Do AR series routers support Telnet
All AR series routers support Telnet. On AR routers earlier than V200R005C30, Telnet is enabled by default. On AR routers of V200R005C30 and later, Telnet is disabled by default. Run the telnet [ ipv6 ] server enable command to enable Telnet.

Does the LTE cellular interface support PPP
The LTE cellular interface supports PPP. The following physical interfaces also support PPP: - Synchronous or asynchronous serial interface working in synchronous mode (the interface type is the serial interface) - Async interface working in protocol mode - Serial interfaces formed by CE1/PRI or CT1/PRI interfaces, which have the same logical features as synchronous serial interfaces - Serial interfaces formed by CE3 or CT3 interfaces, which have the same logical features as synchronous serial interfaces - Serial interfaces formed by E1-F or T1-F interfaces, which have the same logical features as synchronous serial interfaces - Serial interfaces formed by E1/T1 channels that are channelized from a CPOS interface, which have the same logical features as synchronous serial interfaces - Cellular interfaces - ISDN BRI interfaces - POS interfaces Note: For LTE cellular interfaces, only the E392 data cards support the link-protocol ppp command.

Do AR routers support URL filtering
The support on URL filtering of AR routers varies with versions. The deep security function includes the URL filtering function and the IPS function. A device that does not support the deep security function does not support URL filtering. - In V200R005C10, V200R005C20, and V200R005C21: Except for AR150, AR160, AR200, AR1200, and AR2200 series (AR2201 and AR2202), all models support the deep security function. - In V200R005C30, V200R005C31, and V200R005C32: Only AR160 series (AR169FVW, AR169FGW-L, and AR169FGVW-L), AR2200 series (AR2204, AR2220, AR2220L, and AR2240), and AR3200 series support the deep security function. - In V200R006C10: Only AR160 series (AR169FVW, AR169FGW-L, AR169FGVW-L, AR169BF, and AR161FW), AR1200 series (AR1220E, AR1220EV, and AR1220EVW), AR2200 series (AR2204, AR2220, AR2220L, AR2220E, and AR2240), and AR3200 series support the deep security function. - In V200R007C00: Only AR160 series (AR169FVW, AR169FGW-L, AR169FGVW-L, AR169BF, and AR161FW), AR1200 series (AR1220E, AR1220EV, and AR1220EVW), AR2200 series (AR2204, AR2220, AR2220L, AR2220E, AR2240, and AR2240C), and AR3200 series support the deep security function. - In all versions: Only AR1200-S series (AR1220E-S) support the deep security function.
