S5730S-EI Service Port Stacking
Support
S5730S-EI Service Port Stacking
Support
For the cables that can be used as stack cables,
see "Cables" in the Hardware Description. Using other cables
may cause exceptions in the stack system, for example, frequent error-down
events on stack ports.
Combo ports cannot function as stack member ports.
For stacking-supported service ports, some
of them can be used as stack ports, whereas some can be used as ordinary
service ports.
Stack card stacking and service port stacking (including
ordinary cable stacking and dedicated stack cable stacking) cannot
be used together. If service port configurations are correct, service
port stacking is preferred over stack card stacking. If stack card
stacking has been used to set up a stack, to use service port stacking
to set up the stack, you need to restart the stack to make service
port stacking takes effect after configuring service port stacking.
40GE ports on interface card cannot be used
together with 40GE ports on the ES5D21VST000 stack card to set up a
stack.
S5730S-EI series switches of all
versions can set up stacks in service port stacking mode using dedicated
stack cables.
The number of stacked switches is recommended
to be 2 to 9.

S5730S-EI
10GE optical ports on the front panel
1 m, 3 m, and 5 m SFP+ passive high-speed copper cables
10 m SFP+ active high-speed copper cables
3 m and 10 m AOC cables
10GE SFP+ optical module and optical fiber
0.5 m and 1.5 m SFP+ dedicated stack cable
10Gbit/s
Any models of the S5730S-EI series can set up a stack.
When 40GE optical ports are used as stack ports, a switch supports a maximum
of two logical stack ports, and each logical stack port supports at
least one stack member port and at most four stack member ports. A
switch supports a maximum of four stack member ports.
When 10GE ports are used as stack ports, a switch supports a maximum
of two logical stack ports, and each logical stack port supports at
least one stack member port and at most eight stack member ports.
A switch supports a maximum of eight stack member ports.
Two types of ports on an S5730S-EI can both be configured
as stack member ports, but each logical stack port contains only the
same type of stack member ports.
40GE ports do not support the stacking function
after they are split into 10GE ports.
If stack member ports on the front panel are connected
using 1 m, 3 m, or 5 m QSFP+ passive high-speed copper cables, their
working speed can be increased to 48 Gbit/s using the stack
port speed command. After their working speed is increased
to 48 Gbit/s, switches using these ports cannot set up a stack with
switches using ports with the working speed 40 Gbit/s.
