Guidelines and Limitations for F1 Series Module

Guidelines and Limitations for F1 Series Module
• Multiple SPAN destinations are not supported when an F Series module is present in a VDC. If multiple
• A FabricPath core port is not supported as a SPAN destination when an F Series module is present in a
• F1 Series modules are Layer 2 domain modules. Packets from Layer 3 sources can be spanned and
• When using SPAN sessions on F1 Series or F2 Series modules, ensure that the total amount of source
• MTU truncation and the SPAN rate limit are supported on F Series and M2 Series modules and Supervisor
• For F1 Series modules, MTU truncation on egress spanned FabricPath (core) packets has 16 fewer bytes
• For certain rate limit and packet size values on F Series modules, M2 Series modules, and Supervisor
• SPAN sampling is supported only on F Series modules.
• Traditional SPAN sessions support traffic from the F Series and M Series modules. Extended SPAN
• F1 Series modules have limited support for rule-based SPAN. They do not support IPv6 source IP and

• F2e modules with Release 6.1(x).
• For F3 series modules with Release 6.2.6, the FabricPath (FP) header is not preserved.
SPAN destinations are configured in a SPAN session, the session is disabled until the F Series module
is powered down or moved to another VDC or the multiple SPAN destinations are reduced to a single
destination.

directed to an F1 Series module SPAN destination. An F1 Series module interface cannot be configured
as Layer 3, but it can receive Layer 3 traffic in a SPAN destination mode.
traffic in a given session is less than or equal to the capacity of the SPAN destination interface or port
channel for that session. If the SPAN source traffic exceeds the capacity of the SPAN destination, packet
drops might occur on the SPAN source interfaces. This guideline does not apply to F2e, F3 or M3 Series
modules.

You cannot enable MTU truncation and the SPAN rate limit for the same SPAN session

on F1 Series modules. If you configure both for one session, only the rate limit is allowed
on F1 Series modules, and MTU truncation is disabled until you disable the rate limit
configuration. This limitation does not apply to F2 and M2 Series modules or Supervisor

than the configured value because the SPAN destination removes the core header. In addition, when
trunk ports are used as the SPAN destination, the spanned ingress packets have 4 more bytes than the
configured MTU truncation size.
2, the SPAN packet rate is less than the configured value because of the internal accounting of packet
sizes and internal headers.
sessions support traffic only from the F Series and M2 Series modules.
IPv6 destination IP filters. They support only IPv4 and IPv6 ToS filters with values from 0 to 3. Port
channel member lane, FCoE source ID, and FCoE destination ID are not supported.
