Advanced Security
Advanced Security Activation is designed to enables policy-based security
mechanisms integrated within Fabric Operating System V2.6, and later. To enable
advanced security capabilities, all switches within the IBM SAN Switch Fabric must
be configured with their respective Fabric operating system version (2.6 or later)
before activating the Advanced Security feature license key. When activated across
the IBM SAN Switch Fabric, the Advanced Security Activation feature supports the
following security capabilities:
v Centralized security management (trusted switches)
v Fabric-wide security policies to control access
v Port-level access control
v Switch-level access control
v Management access controls (Telnet, SNMP, HTTP, API)
v Encryption of management data such as passwords
v Strong and non-reputable authentication between switches
Performance Bundle (Performance Monitoring and ISL Trunking)
Performance Bundle Activation is a plant order only feature consisting of both
Enhanced Inter-Switch Link (ISL) Trunking and Performance Monitoring capabilities.
Activation of either feature can be ordered separately for field installation.
Performance Monitoring helps identify end-to-end bandwidth usage by host/target
pairs and is designed to provide information for capacity planning. Trunking enables
Fibre Channel packets to be efficiently distributed across multiple Inter-Switch
connections (links) between two SAN b-type fabric switches, while preserving
in-order delivery. Both SAN b-type fabric switches must have ISL Trunking
activated.
ISL Trunking
Enhanced ISL Trunking is supported between two SAN16B-2, SAN32B-2, or
SAN256B 4-Gbps models and enables Fibre Channel packets to be distributed
across up to eight 4 Gbps-capable ISLs for a combined bandwidth of up to 32
Gbps. When connecting the 4 Gbps-capable switches to earlier 2-Gbps b-type
fabric switch models, ISL Trunking is supported with link speeds operational at 2
Gbps and Fibre Channel packets distributed across up to four ISLs for a combined
bandwidth of up to 8 Gbps.
If your switch is licensed for ISL Trunking, use the trunking groups available on the
switch. For the SAN16B-2, the maximum number of ports per trunk is four. The
Fibre Channel ports are numbered from left to right, color-coded into groups of four
to indicate the groups of ports that can be used in the same interswitch link (ISL)
trunking group. The number of trunked lines can be from two through four ports
within a single trunk group. The trunk groups are shown in Figure 2 on page 5.
