Virus Throttling (5300xl Switches Only) 
Basic Connection-Rate Filtering Configuration 
Note  HP recommends that, before you unblock a host that has been blocked by 
connection-rate filtering, you inspect the host with current antivirus tools and 
remove any malicious agents that pose a threat to your network. 
If a trusted host frequently triggers connection-rate blocking with legitimate, 
high connection-rate traffic, then you may want to consider either changing 
the sensitivity level on the associated port or configuring a connection-rate 
ACL to create a filtering exception for the host. 
Syntax:  vlan < vid > connection-rate-filter unblock < all | host  | ip-addr > 
all: In the specified VLAN, unblocks all hosts currently blocked 
due to action by connection-rate filtering on ports where 
block mode has been configured. 
host < ip-addr >: In the specified VLAN, unblocks the single 
host currently blocked due to action by connection-rate 
filtering on ports where block mode has been configured. 
ip-addr < mask > : In the specified VLAN, unblocks traffic 
from any host in the specified subnet currently blocked due 
to action by connection-rate filtering on ports where block 
mode has been configured. 
Note  Rebooting the switch unblocks all hosts affected by a connection-rate filter 
block.
