The ESRP Manager
Figure 176: ESRP Manager showing summary ESRP-enabled VLAN status
This display shows a summary of the ESRP configuration for each ESRP-enabled VLAN.
The information displayed is as follows:
• VLAN Name —The name of the ESRP-enabled VLAN.
• Master Switch —The name, if known, or MAC address of the switch currently designated as the
Master switch. If this switch is being managed by EPICenter (is included in EPICenter’s Inventory
database) the name will appear. If the switch is not known to EPICenter, the MAC address will
appear.
• IP Address
—The IP address of the ESRP-enabled VLAN. If the master switch is not known to
EPICenter, this will be “N/A.”
• Group —The ESRP group to which this ESRP-enabled VLAN belongs in a broadcast domain that
contains multiple instances of ESRP (multiple ESRP groups). The names of the ESRP-enabled VLANs
participating in the same group must be identical.
• Election Algorithm —The ESRP election algorithm in use for this VLAN. The election algorithm
determines the order of precedence of the election factors used to determine the ESRP Master. The
election factors are:
— Ports: the number of active ports (the switch with the highest number takes priority)
— Track: whether the switch is using ESRP tracking (a switch using tracking has priority)
— Priority: a user-defined priority number between 0 and 254 (a higher number has higher priority)
—
MAC: the switch MAC address (a higher-number address has priority)
