Skybox Appliance 5500 Quick Start Guide
Skybox version 8.5.400
22
mode=3 (broadcast)
Broadcast policy: transmits everything on all slave interfaces. This mode
provides fault tolerance.
mode=4 (802.3ad)
IEEE 802.3ad Dynamic link aggregation. Creates aggregation groups that share
the same speed and duplex settings. Utilizes all slaves in the active aggregator
according to the 802.3ad specification.
Pre-requisites:
1
Ethtool support in the base drivers for retrieving the speed and duplex of each
slave.
2
A switch that supports IEEE 802.3ad Dynamic link aggregation. Most switches
will require some type of configuration to enable 802.3ad mode.
mode=5 (balance-tlb)
Adaptive transmit load balancing: channel bonding that does not require any
special switch support. The outgoing traffic is distributed according to the current
load (computed relative to the speed) on each slave. Incoming traffic is received
by the current slave. If the receiving slave fails, another slave takes over the
MAC address of the failed receiving slave.
Prerequisite:
›
Ethtool support in the base drivers for retrieving the speed of each slave.
mode=6 (balance-alb)
Adaptive load balancing: includes balance-tlb plus receive load balancing (rlb) for
IPV4 traffic, and does not require any special switch support. The receive load
balancing is achieved by ARP negotiation. The bonding driver intercepts the ARP
replies sent by the local system on their way out and overwrites the source
hardware address with the unique hardware address of one of the slaves in the
bond such that different peers use different hardware addresses for the server.
RADIUS authentication
This topic explains how to configure RADIUS authentication for Skybox Appliance.
Note: To use RADIUS authentication, the
pam_radius
package must be installed
on the Skybox Server. You can check whether it is installed using the
rpm
–qa|grep pam_radius
command. If you need help installing it, contact
To configure RADIUS authentication
1
Open
/etc/pam.d/sshd
in your editor and find the following 2 lines:
#Radius module to be used with Radius server
auth sufficient pam_radius_auth.so
