  Media-type CLI command  
Added new command "media-type" to configure an interface to select the specified media on a combo port.  It is 
recommended the administrators select the specific media type for the particular type of network connection they 
expect to use.  Users may observe a single port flap when the media type is changed from RJ45 to auto-select RJ45 and 
only the corresponding SFP port is enabled. Refer to the CLI Reference Guide Updates section below for the complete 
syntax. 
Release 4.1.0.6 
  IPv4-Only Mode Optimization 
PowerConnect switches allocate the maximum sizes for routing tables (and others, as applicable) for both IPv4 and 
IPv6.  Switch Performance Optimization allows the operator to optimize the allocation of switch silicon tables for 
either IPv4 only or mixed IPv4/IPv6 operation.  The template specified limits are enforced by routing components 
when routes are being learned. When IPv4 only mode is selected, the following capabilities are disabled: 
 
•  DHCPv6 relay 
•  DHCPv6 server 
•  IPv6 routing/forwarding 
•  OSPFv3 
•  IPv6 Neighbor Discovery 
•  Configured v6-over-v4 tunnels 
•  Automatic (6to4) tunnels 
•  IPv6 Multicast 
 
A reboot is required when changing to or from IPv4 mode.
