Irf Physical Interface Requirements - H3C S6820 Configuration Examples

IRF physical interface requirements

Candidate IRF physical interfaces
Use the following ports as IRF physical interfaces:
•
SFP28 ports operating at 25 Gbps.
•
QSFP+ ports operating at 40 Gbps.
•
QSFP28 ports operating at 40 Gbps or 100 Gbps, or their 25-GE breakout interfaces.
The ports on LSWM18CQMSEC modules cannot be used as IRF physical interfaces.
Grouped port binding restrictions
The S6820 switch series contains grouped ports, as shown in
When you use the ports in a group for IRF links, follow these restrictions and guidelines:
•
If you use one port in a group as an IRF physical interface, the remaining ports in the group can
only act as IRF physical interfaces. You cannot use them for any other purposes. If you use only
some of them for IRF connection, the remaining ports can only be idle.
•
The ports in a group can be bound to different IRF ports.
•
Before you bind one port to an IRF port, you must shut down all the ports that have not been
bound to IRF ports. If any of the unbound ports are in up state, the bind action will fail.
•
Before you remove one port from an IRF port, you must shut down all the ports. If any of the
ports are in up state, the remove action will fail.
•
Bring up the ports after you complete the bind operation. If a port is not bound to an IRF port, the
system prevents you from bringing up the port so it cannot be used for purposes other than IRF
connection.
NOTE:
These restrictions on gouped ports do not apply if you use 100-GE ports that are not split or use
40-GE ports (except ports on the LSWM116Q module) for IRF connections.

Port grouping rules
The switch has two fixed port ranges. Ports numbered
1 to 24 are in one range and ports numbered 33 to 56
are in the other range. In each range, the ports are
divided into four-port groups by port number in order,
starting from the lowest number.
The ports numbered 1 to 24 are divided into four-port
groups by port number in order, starting from 1.
Odd and even numbered ports are grouped separately
into two-port groups by port number, starting from the
lowest odd or even number. Each group contains two
ports with consecutive odd or even port numbers. For
example, ports 1 and 3 are in one group, and ports 2
and 4 are in another group.
The four 25-GE breakout interfaces of a 100-GE port
are in one port group. To split a 100-GE port, use the
using twenty-fivegige command.
