Hot standby
Hot standby
Hot standby redundancy is a backup feature that allows a ServerIron to serve as an automatic
backup for another ServerIron. Each hot-standby pair consists of two ServerIrons. One ServerIron
serves as the primary or active ServerIron, and the other serves as the secondary or standby
ServerIron. The standby ServerIron becomes active only if the primary ServerIron fails due to loss of
power or loss of data path. The active and standby ServerIrons must have the same SLB or TCS
configuration and share the same virtual MAC address. The shared MAC address can be selected
from the available pool on either the active ServerIron or the standby ServerIron.
For more information on the Hot standby feature, refer to the Brocade ServerIron Firewall Load
Balancing Guide.
The following objects apply to the Hot standby redundancy feature.
snL4slbDangling
brcdIp.1.1.4.1.9
Syntax: Integer Read only Shows the number of old types of connections. For use by Foundry
technical support.
snL4slbDisableCount
brcdIp.1.1.4.1.10
Syntax: Integer Read only Shows the number of packets the ServerIron dropped because they
were sent by a client to a VIP port that is bound to a disabled real server
port.
snL4slbAged
brcdIp.1.1.4.1.11
Syntax: Integer Read only Shows the total number of TCP and UDP sessions that have been aged
out and closed. A session ages out when the age timer configured on
the ServerIron expires.
snL4slbFinished
brcdIp.1.1.4.1.12
Syntax: Integer Read only The total number of TCP connections that are either in the FIN or RST
state.
snL4unsuccessfulConn
brcdIp.1.1.4.1.25
Syntax: Integer Read only Shows the number of packets that were dropped due to one of the
following reasons:
•
A deny filter configured on the switch matched the packet, causing
the switch to drop the packet.
•
A client requested a TCP or UDP port that is not bound on the VI.
Name, OID, and Syntax Access Description
Name, OID, and Syntax Access Description
snL4BackupInterface
brcdIp.1.1.4.1.14
Syntax: Integer Read-write Identifies which port is the hot standby port. This is the port that serves
as a private link between the active and the redundant ServerIrons. The
ServerIrons use this port to monitor any failover and to communicate
those events to the standby.
Valid values: 0 – 26
snL4BackupMacAddr
brcdIp.1.1.4.1.15
Syntax: Physical address Read-write Identifies the associated MAC address for the backup monitoring port.
The active and backup ServerIron must have the same MAC address.
snL4Active
brcdIp.1.1.4.1.16
Syntax: L4flag Read only The “snL4Redundancy” object and this object are the same.
Indicates if this ServerIron has been configured as redundant or hot
standby:
•
false(0) – This ServerIron is the active one.
•
true(1) – This ServerIron is the standby.
