Stack MAD

Hello Hobbit,

1. You can use only one eth-trunk as the picture already shows.

2. The same function is called DAD instead of MAD on CE switches. When the CE8860 uses DAD proxy mode to detect the stack, the  S12700 can be DAD proxy; but when S12700 uses MAD proxy mode to detect the stack, the CE8860 can’t be the MAD proxy.

I hope this helps.

I don't quite understand your answer to the second question,
Can you please provide me some configuration or more details, please.
My understanding is that if I want to use S12700 as a DAD relay for the CE, this is possible. But I cannot use the CE as a relay for the 12700. So it’s like a one-way operation.

Yes, it’s a one-way operation.

Below you can find a configuration example for CE and S Switch:

CE configuration

#

interface 10GE1/0/5

eth-trunk 10

#

interface 10GE2/0/5

eth-trunk 10

#

interface Eth-Trunk10

dual-active detect mode relay

#

return

S configuration

#

interface GigabitEthernet1/0/19

eth-trunk 1

#

interface GigabitEthernet1/0/21

eth-trunk 1

#

interface Eth-Trunk1

mad relay

return

Please tell me if there is anything else I can help you.
