Suppressing SNMP notifications of packet drops on IRF physical interfaces
Before an IRF member device forwards a packet, it examines its forwarding path in the IRF fabric for
a loop. If a loop exists, the device discards the packet on the source interface of the looped path.
This loop elimination mechanism will drop a large number of broadcast packets on the IRF physical
interfaces.
To suppress SNMP notifications of packet drops that do not require attention, do not monitor packet
forwarding on the IRF physical interfaces.

Feature Feature compatibility and configuration restrictions
Routing
To form an IRF fabric, all member devices must use the same settings for
the following routing features:
•
Maximum number of ECMP routes (set by using the
max-ecmp-num command).
•
ECMP mode (set by using the ecmp mode command).
For more information about the routing features, see basic IP routing
configuration in
Layer 3—IP Routing Configuration Guide .
Layer 2 forwarding IRF ports cannot forward Layer 2 traffic.
Link aggregation Multichassis Layer 2 link aggregation is not supported.
IPsec
IPsec anti-replay requires that packets on the same interface be
processed on the same slot. For information about how to perform IPsec
anti-replay on an IRF fabric for a global interface (such as a VLAN or
tunnel interface) that has physical interfaces across slots, see IPsec in
Security Configuration Guide .
Session
Session backup is not supported between member devices. The packets
must be sent and received on the same member device for services that
require session establishment. Examples of these services include NAT,
ASPF, and AFT.
Dialing Not supported on the AUX, AM, or ISDN interfaces in IRF mode.
Web network management Not supported in IRF mode.
Built-in AC Not supported in IRF mode.
VLAN
In IRF mode, Ethernet switching modules on the master and subordinate
devices must support the same maximum number of VLANs.
Licensing requirements for IRF
For a license-based feature to run correctly on an IRF fabric, make sure the licenses installed for the
feature on all member devices are the same. For more information about feature licensing, see
Fundamentals Configuration Guide .
Configuration rollback restrictions
The configuration rollback feature cannot roll back the following IRF settings:
