Switches

The purpose of this document is to provide more detailed descriptions of our managed network switches.

FHILL

FHILL our primary fiber switch on the hill campus. It is a Mikrotik CRS326-24S+2Q+RM running RouterOS v7. The management interface is assigned to 128.153.145.21, and is currently accessible from within the lab network. If in doubt, the Ethernet port labeled MGMT/BOOT should always be configured to allow access to the management interface.

PortsCount
SPF+ (10G)24
QSPF+ (40G)2
Ethetnet (100M)1

The switch is physically split into 3 groups of 8 SFP+ ports and 1 group containing the 2 QSFP+ ports. It also has a 100M Ethernet port for management.

STP

Kasper is currently configured as a filtered bridge between cosi_pub and cosi_priv. STP will detect this as a loop, because even though both ports are on separate VLANs, they are on the same bridge on the switch. To solve this STP has been disabled entirely on FCOLO.
