Question

A network engineer deployed a switch that operates the LAN base feature set and decides to use the SDM VLAN template. The SDM template is causing the CPUof the switch to spike during peak working hours. What is the root cause of this issue?A.The VLAN receives additional frames from neighboring switches.B.The SDM VLAN template causes the MAC address-table to overflow.C.The VLAN template disables routing in hardware.D.The switch needs to be rebooted before the SDM template takes effect.

Answer 1

Answer:

C.The VLAN template disables routing in hardware.

Explanation:

The SDM Template Notes states All templates are predefined. There is no way to edit template category individual values.

The switch reload is required to use a new SDM template.

The ACL merge algorithm, as opposed to the original access control entries (ACEs) configured by the user, generate the number of TCAM entries

listed for security and QoS ACEs.

The first eight lines (up to Security ACEs) represent approximate hardware boundaries set when a template is used. If the boundary is exceeded, all

processing overflow is sent to the CPU which can have a major impact on the performance of the switch.

Choosing the VLAN template would then disable routing  in hardware.
