How to check connectivity between two servers
DHCP is a network protocol that uses a DHCP server to control the distribution of network parameters, such as IP addresses, allowing systems to automatically request these parameters.
HOW TO CHECK CONNECTIVITY BETWEEN TWO SERVERS SERIES
If you wish to configure redundant NICs on the same subnet, us e NIC teaming.īy default, Dynamic Host Configuration Protocol (DHCP) is enabled for your B Series Appliance. These switches drop all packets received from eth1 since this NIC does not have the default gateway and is not present in the static ARP table of the gateway. Some switches are configured with static ARP.
When eth0 receives these packets from the switch destined for eth1, eth0 drops the packets. Switches configured with dynamic ARP send packets randomly to either eth0 (192.168.1.5) or eth1 (192.168.1.10), not both. Given this configuration, traffic from both NICs are sent to the default gateway (192.168.1.1) regardless of which NIC received traffic. Both eth0 and eth1 are connected to the same subnet switch.Consider the following example configuration:Įth0 is configured with the default gateway of 192.168.1.1 In this scenario, packet loss occurs with packets originating from the IP on the NIC that does not have the default gateway. If you are using a Virtual or Cloud Appliance environment, the Enable NIC Teaming option is not available.Īlthough multiple IP addresses can be assigned to each NIC, do not configure either NIC such that it has an IP address that is in the same subnet as an IP address on the other NIC.
Before activating NIC teaming, please ensure that both NICs are connected to the same network segment (subnet) and that you have IP addresses configured on only one of the existing NICs. If the link on that NIC is lost for any reason, the other NIC becomes active. One of the NICs is used to carry all network traffic. NIC teaming operates in "Active-Backup" mode. NIC teaming combines your system's physical network interface controllers (NICs) into a single logical interface. For example, if employees are restricted from accessing the internet but need to provide off-network support, using one port for your internal private network and another for the public internet allows users worldwide to access systems without breaching your network security policies. Using multiple ports can enhance security or enable connections over non-standard networks.
