The equivalent information can be retrieved in SNMP using new entries in the
statSystem table:
- statSystemRedunMacAddrState1
- statSystemRedunMacAddr1
- statSystemRedunMacAddrState2
- statSystemRedunMacAddr2.
• Modified: An ARP request is now sent to the ARP cache 1 minute before the
Time To Live (TTL) ends if the NetPerformer needs to send a packet to a specific
MAC address. This ensures that the entry for this MAC address will not be
erased from the ARP table. It also prevents traffic bursts when ARP entries are
renewed.
• Modified: The DISPLAY operation of the ARP command now includes the port
index of the LAN interface. This distinguishes entries in the ARP cache with the
same destination address, and resolves a problem with SNMP.
