Default Network
Uplink
By default, we deliver servers with a single uplink.
LLDP
LLDP – Link Layer Discovery Protocol is disabled within the Worldstream network. Our expertise has led us to disable LLDP on interfaces facing the Worldstream network. LLDP can send data about the local network device or server with sensitive data about the device, this data might contain details about firmware versions and possible bugs or backdoors. Due to this risk Worldstream decided to disable LLDP packets on customer facing interfaces.
Spanning Tree Protocol (STP)
Spanning-tree is not passed through within the Worldstream network. All BPDU’s received on the Worldstream switch will be dropped and filtered from being forwarded. This decision is made to prevent interaction in the STP topology between the Worldstream and customer network. Topology change notifications might interrupt forwarding traffic for customers in these situations. The customer will be responsible for its own STP domain without the capability to join or forward BPDU’s within the Worldstream network.
Storm Control
Customer facing ports are set up with a maximum amount of multicast, unknown unicast, and broadcast traffic. This security measure is configured in case of an ongoing loop. When the Worldstream switch receives more than the configured limit (limit is set in packets per second and % of the current speed) than the configured limit, the traffic will be dropped.
Levels are set to:
- Multicast: 1% of the current link speed
- Broadcast: 1% of the current link speed
MTU Size
A maximum MTU size of 1500 is allowed (this includes the packet headers).
IPv6 Neighbor Limit
Configured IPv6 services are assigned with a prefix of /48 or smaller (by default /64). The number of hosts within these subnets have the capability of overloading the switch’ maximum hardware count. A maximum of 500 IPv6 hosts are allowed per IPv6 subnet to prevent spoofing attacks.
