Change the Default Gateway of a TPVM

You can change the default gateway of a TPVM.​

About this task

Follow this procedure to change the default gateway of a TPVM for the IPv4 IP-Stack.

You can use this procedure for Dual IP-Stack type with Dual static IP configuration. For more information, see Configure Static IP Addresses for Management Sub Interfaces.

This procedure does not affect the functioning of XCO high-availability mode.

  • The gateway IP address must be in the same subnet as one of the subinterfaces that are created in XCO.
  • To configure a default gateway for the subinterface subnet, use only static IPv4 addresses.
  • Perform this procedure on both nodes where XCO is deployed, to avoid a loss of XCO functionality.
  • Perform this procedure with caution. XCO and SLX-OS do not validate reachability of the gateway during this operation.
  • Vital services, such as DNS, NTP, and LDAP, must be reachable from the new gateway.

Procedure

  1. Add static IP addresses to the sub interface.
    You can assign a maximum of one pair of static IP addresses. Only one sub interface at a time can have static IP addresses.
    efa mgmt subinterface staticip --name <sub-int-name> --ip1 <ip-addr> 
    --ip2 <ip-addr>
  2. Change the gateway of the standby TPVM.
    efa inventory device execute-cli --ip <standby-slx-ipaddr> 
    --command "tpvm TPVM,interface management ip <standby-tpvm-ipaddr> 
    gw <new-gateway-ipaddr>" --config
  3. Change the gateway of the active TPVM.
    efa inventory device execute-cli --ip <active-slx-ipaddr> 
    --command "tpvm TPVM,interface management ip <active-tpvm-ipaddr> 
    gw <new-gateway-ipaddr>" --config
