Hitless management on the FSX 800 and FSX 1600

Layer 3 IPv6 routed traffic • BGP4+
• IPv6 unicast forwarding
• OSPFv3
• OSPFv3 with ECMP
• Static routes
• VRRP
• VRRP-E
Layer 3 routed traffic for supported protocols is not
impacted during a Hitless management event. Traffic
will converge to normalcy after the new active module
becomes operational.
Other Layer 3 protocols that are not supported will be
interrupted during the switchover or failover.
If BGP4+ graceful restart or OSPF graceful restart /
OSPFv3 NSR is enabled, it will be gracefully restarted
and traffic will converge to normalcy after the new
active module becomes operational. For details about
OSPFv3 graceful restart, refer to “OSPF v3 graceful
restart” section in the FastIron Ethernet Switch Layer 3
Routing Configuration Guide. For details about BGP4
graceful restart, refer to “BGP4+graceful restart”
section in the FastIron Ethernet Switch Layer 3 Routing
Configuration Guide.
Configured ACLs will operate in a hitless manner.
Management traffic N/A All existing management sessions (SNMP, TELNET,
HTTP, HTTPS, FTP, TFTP, SSH etc.), are interrupted
during the switchover or failover process. All such
sessions are terminated and can be re-established
after the new Active Controller takes over.
Security
• 802.1X, including use with dynamic ACLs
and VLANs
• IPv4 ACLs
• IPv6 ACLs
• DHCP snooping
• Dynamic ARP inspection
• EAP with RADIUS
• IP source guard
• Multi-device port authentication, including
use with dynamic ACLs and VLANs
Supported security protocols and services are not
impacted during a switchover or failover.
NOTE: If 802.1X and multi-device port authentication
are enabled together on the same port, both
will be impacted during a switchover or failover.
Hitless support for these features applies to
ports with 802.1X only or multi-device port
authentication only.
Configured ACLs will operate in a hitless manner,
meaning the system will continue to permit and deny
traffic during the switchover or failover process.
Other services to
Management
• AAA
• DHCP
• sFlow
• SNMP v1, v2, and v3
• SNMP traps
• NTPv4
• Traceroute
Supported protocols and services are not impacted
during a switchover or failover.
DNS lookups will continue after a switchover or failover.
This information is not synchronized.
Ping traffic will be minimally impacted.
