DHCP configuration does not take effect on the AR

1

Possible causes are as follows:
1. DHCP is not enabled on the AR.
2. The address pool is configured incorrectly.
3. The IP network segment is not specified on the interface of the DHCP server connected to the client, or the specified IP network segment and address pool are different.
4. If ACL resources are used up, the DHCP command that is run globally or on an interface does not take effect.

DHCP configuration on S series switch does not take effect
DHCP configuration may not take effect on an S series switch due to the following reasons: 1. DHCP server is disabled on the switch. 2. The DHCP address pool is configured incorrectly. 3. No IP network segment is specified on the interface connected to DHCP clients, or the specified IP network segment is on a different network segment from the address pool. 4. If ACL resources are exhausted, the DHCP commands run globally or on an interface will not take effect.

Why a traffic policy does not take effect on an AR
Pay attention to the following points when configuring a traffic policy so that the traffic policy can take effect: - In a traffic behavior, when the permit action is configured with other actions, the device performs these actions one by one. The deny action cannot be used with other actions (except traffic statistics and traffic mirroring); even if they are configured together, only the deny action takes effect. - When packets are filtered based on an ACL rule, if the rule is configured to permit, the action taken on the packets is decided by the deny or permit action configured in the traffic behavior. If the rule is configured to deny, packets are discarded no matter whether the deny or permit action is configured in the traffic behavior. - A traffic policy that contains the following traffic behaviors can be applied only in the outbound direction of a WAN interface: traffic shaping, adaptive traffic shaping, congestion management, and congestion avoidance. - After fragmentation is configured on an AR, if the rule of the traffic classifier contains the non-first-fragment field, the rate limiting or statistics collection function cannot be configured for the fragmented packets sent to the AR. - If a traffic behavior is bound to an ACL that has no rule configured, the traffic policy referencing the ACL does not take effect.

Whether S series switches support IPv6
The IPv6 function of S series modular switches is controlled by a license. By default, the IPv6 function is disabled on a new switch. To use the IPv6 function, apply for and purchase the license from the equipment supplier. - For details about products and versions of the S12700 sereis switches supporting IPv6, see Basic IPv6. - For details about products and versions of the S7700&S9700 sereis switches supporting IPv6, see Basic IPv6. - For details about products and versions of the S9300 sereis switches supporting IPv6, see Basic IPv6. - For details about products and versions of fixed switches supporting IPv6, see Basic IPv6.
