Hi

There is a stack, made from different Extreme Networks Summits

* Slot-1 Stack.33 # sh stacking
Stack Topology is a Daisy-Chain
Active Topology is a Daisy-Chain
Node MAC Address    Slot  Stack State  Role     Flags
------------------  ----  -----------  -------  ---
 00:04:96:34:8a:4d  3     Active       Standby  CA-
 00:04:96:37:26:eb  2     Active       Standby  CA-
*00:04:96:52:1f:0d  1     Active       Master   CA-

The problem is in HW Route Table in non-master slots

* Slot-1 Stack.37 # show iproute reserved-entries statistics
                       |-----In HW Route Table----|   |--In HW L3 Hash Table--|
                       # Used Routes   # IPv4 Hosts   IPv4   IPv4   IPv6  IPv4
Slot  Type              IPv4   IPv6    Local Remote   Local  Rem.   Loc.  MCast
----  ---------------- ------ ------  ------ ------   -----  -----  ----  -----
1     X480-24x(SS)      11115      0    1040      0       0      0     0    205
2     X450a-24t         11115      0      48      0     992      0     0    205
3     X450a-24t         11115      0      48      0     992      0     0    205

Hi, Igor!

You can mix Summit X460, X480, and X670 switches in a stack, Extreme Networks recommends that you do not mix these switch types if the desired routing table exceeds the supported limit for the Summit X460 switch, which is 12,256 IPv4 LPM routes.

In your case X450a have this limit too.

Thank you!

Hey Igor

The master is what controls all of the L2 and L3 tables and getting them filled within the stack.  There is no way to disable L3 on a particular slot.  As Alexandr says above when there is a mixed stack the route table of the whole stack is whatever the lowest size table is.  So if one switch has a table size of 32K and one has a table of 64K the overall stack is 32K.

Thanks
