Does an AR support inter-card Eth-Trunk

51

Only 8FE1GE and 24GE cards support inter-card Eth-Trunks. 4GE-2S, 4ES2G-S, 4ES2GP-S, and 9ES2 cards do not support inter-card Eth-Trunks.

Does S series switch support inter-chassis Eth-Trunk
The S series switches support inter-chassis Eth-Trunk. The Eth-Trunks on different stand-alone switches can form an E-Trunk. An E-Trunk protects the links between the CE and PEs and implements backup between PEs.

Does an S series modular switch support inter-card redirection
S series modular switches support inter-card redirection for incoming traffic. A switch can redirect flows that meet certain conditions to the CPU, other interfaces, or other IP addresses. Do as follows to configure the redirection function: 1. Configure an ACL rule. [HUAWEI] acl number 3000 [HUAWEI-acl-adv-3000] rule 0 permit ip source 192.168.1.1 0 [HUAWEI-acl-adv-3000] quit 2. Configure a traffic classifier. [HUAWEI] traffic classifier 3000 [HUAWEI-classifier-3000] if-match acl 3000 [HUAWEI-classifier-3000] quit 3. Configure a traffic behavior. [HUAWEI] traffic behavior 3000 [HUAWEI-behavior-3000] redirect interface GigabitEthernet 4/0/0 [HUAWEI-behavior-3000] quit 4. Configure a traffic policy. [HUAWEI] traffic policy 3000 [HUAWEI-trafficpolicy-3000] classifier 3000 behavior 3000 [HUAWEI-trafficpolicy-3000] quit 5. Apply the traffic policy to an interface. [HUAWEI] interface GigabitEthernet 3/0/0 [HUAWEI-GigabitEthernet3/0/0] traffic-policy 3000 inbound [HUAWEI-GigabitEthernet3/0/0] quit

Do AR routers support inter-card MP
In V200R005 and earlier versions: The devices do not support inter-card MP. In V200R006 and later versions: The devices support only the MP across interface cards of the same type. 1STM1, 1STM4, 4STM1, 1CPOS-155M, and 1CPOS-155M-W interface cards do not support inter-card MP. 1SA/2SA/8SA, 1E1/T1-M, 2E1/T1-M, 4E1/T1-M, 8E1/T1-M, 1E3/CE3/T3/CT3, 1E1/T1-F, 2E1/T1-F, 4E1/T1-F, 8E1/T1-F, and 1BST interface cards support inter-card MP.

Is inter-chassis link aggregation supported after a stack of CE switches is set up
Yes It is recommended that the stacked switch connect to the upstream and downstream devices using inter-chassis link aggregation to ensure link reliability.

Do S series modular switches support inter-card mirroring
