Support For Ws-X46490-Csfp-E On A 10-Slot Chassis - Cisco Catalyst 4500 Series Software Configuration Manual

Support for WS-X46490-CSFP-E on a 10-slot Chassis

Starting with Release IOS XE 3.5.0E and IOS 15.2(1)E, the WS-X4640-CSFP-E linecard is supported in a 10-slot chassis for
switch mode stand alone and switch mode virtual (VSS). New configurations are saved and reloaded so that the new
configuration is applied to the entire switch.
To enable support for WS-X4640-CSFP-E on a 10-slot chassis, enter the following:
switch# configuration terminal
switch# hw-module system max-port-num-mode 2
To restore the default mode (Mode 1), you need to enter the following:
switch# configuration terminal
switch# no hw-module system max-port-num-mode 2
OR
switch# configuration terminal
switch# no hw-module system max-port-num-mode 1
OR
switch# configuration terminal
switch# hw-module system max-port-num-mode 1
Mode 1—a default mode in which the switch is configured to max Vfe subports of 48 per linecard; this configuration does
not allow "WS-X4640-CSFP-E" in any of the 8 LC slots.
Mode 2—requires the above configuration to be copied to the startup-config. In this mode, only the first five slots of the
chassis are eligible for the line cards. The remaining three slots are unuseable by any other line card including
WS-X4640-CSFP-E, effectively reducing a 10-slot chassis to a 7-slot. You can place WS-X4640-CSFP-E in the top five
slots, enabling you to use C-Sfp and thereby allow the max 80 ports on each WS-X4640-CSFP-E.
The behavior of a Supervisor Engine 6-E in Mode 2 (which is 10-slot chassis behaving effectively as a 7-slot chassis) matches
that of a 7-slot chassis with Supervisor Engine 6-E. In Mode 2, the supervisor engine WS-X45-SUP6-E with the linecard
WS-X4640-CSFP-E in the 7th slot will be inactive until an uplink mode change (using the hw-module uplink mode
tengigabitethernet command) and a reboot. In this case, a syslog is printed to notify the presence of WS-X4640-CSFP-E in
the 7th slot to prevent you from performing repetitive reboots.
To display the current mode in which the system is running, enter the following:
switch# show hw-module system max-port-num-mode
This command is visible only on 10-slot chassis or if 10-slot chassis is present in VSS.
Note
The output of this command is:
Active max-port-num-mode configuration is 2
In this mode, last 3 Line card slots shall not be active"
In VSS, this output provides the current mode of both active and standby switches.
