show vlt mismatch

Displays mismatches in a VLT domain configuration.

Syntax
show vlt domain-id mismatch [port-security |dhcp-snooping | peer-routing | pim | vlan | vlt-vlan vlt-port-id | virtual-network | private-vlan {mapping | port-mode | vlan-mode} | multicast-snooping | ra-guard | vlan-anycast| dhcp-relay | lacp-individual | evpn | nlb]
Parameters
  • port-security—Displays mismatches in global port-security configurations and all the VLT port-channel port-security configurations.
  • domain-id—Enter the VLT domain ID, from 1 to 255.
  • dhcp-snooping—Display mismatches in a DHCP snooping configuration in a VLT domain.
  • peer-routing—Display mismatches in the peer-routing configuration.
  • pim—Displays PIM mismatch in VLT peers.
  • vlan—Display mismatches in a VLAN configuration in the VLT domain.
  • vlt-vlan vlt-port-id—Display mismatches in the VLT port configuration, from 1 to 4095.
  • virtual-network—Display mismatches in virtual network configurations between VLT peers.
  • private-vlan—Displays mismatches in private VLAN mapping, port mode, or VLAN mode.
  • multicast-snooping—Displays mismatches in IGMP and MLD snooping configuration.
  • ra-guard—Displays mismatches in IPv6 RA guard configuration.
  • vlan-anycast—Display mismatches in VLAN anycast IP configuration between VLT peers.
  • dhcp-relay — Displays the mismatch (if any) between the VLT peers for DHCP relay options configuration on global level and VLANs spanned across the VLT peers.
  • lacp-individual—Displays mismatches in the LACP individual ports between VLT peers.
  • evpn—Displays the ARP-suppression global enabled or disabled mismatch configuration between VLT nodes.
  • nlb—Displays the spanned NLB-cluster VLAN configuration mismatch.

Usage Information

The * in the mismatch output indicates a local node entry.

The show vlt mismatch dhcp-relay command displays the mismatch in the Global ip dhcp-relay information-option command.

The show vlt mismatch dhcp-relay command displays the presence or absence of Interface level ip dhcp-relay information-option configurations.
