CN4093 Application Guide for N/OS 8.3
The following limitations apply:
 UFP and SPAR cannot be configured together.
 LAGs must first be configured for SPAR before they can be used. Static or Link
Aggregation Control Protocol (LACP) LAGs created on the global switch cannot
reference any SPAR ports. Use the commands in the following menus to define
LAGs in the SPAR context:
CN 4093(config)# spar <num>
CN 4093(config-spar)# uplink ?
adminkey Set lacp trunk for uplink
port Set external port for uplink
PortChannel Set portchannel for uplink
CN 4093(config)# portchannel ?
<1-64> PortChannel group
<65-128> LACP PortChannel group
thash Port Channel hash configuration
ACLs defined on the global switch can be used for SPAR ports. However, the

following restrictions apply:
An ACL cannot be shared across SPAR ports if:

• An exit port (CN 4093(config)# access-control list <number>
egress-port port <number>) is used as a filtering criteria and the exit
port does not belong to the same SPAR as the port on which the ACL is
applied.
• A monitor port is used as a filtering criteria, and the monitor port does not
belong to the same SPAR as the mirrored port and is not defined on the
global switch.
These ACL restrictions apply to all ACLs defined in an ACL group.

 Port mirroring can be configured on SPAR ports, but the monitor port must
either belong to the same SPAR as the mirrored port or must be defined on the
global switch.
 Layer 2 failover features can be configured on SPAR ports. However, the Layer 2
failover Auto Monitor (AMON) option is not supported. Only the Layer 2
failover Manual Monitor (MMON) option can be used when all ports defined
within the trigger belong to the same SPAR.
