## Essential Show Commands

### Quick Status Check
```bash
show ip interface brief
show bgp summary
show bgp evpn summary
show mlag
show vxlan vtep
```

### Detailed Verification
```bash
# Underlay
show ip bgp
show ip route
show bgp ipv4 unicast summary

# Overlay
show bgp evpn
show bgp evpn route-type mac-ip
show bgp evpn route-type ip-prefix ipv4

# VXLAN
show interface vxlan1
show vxlan address-table
show vxlan vni
show vxlan config-sanity

# MLAG
show mlag detail
show mlag interfaces
show port-channel summary

# VRF
show vrf
show ip route vrf gold
show bgp ipv4 unicast vrf gold summary
```

## Common Troubleshooting Commands

```bash
# Check BGP neighbors
show ip bgp neighbors <ip>
show bgp evpn neighbors <ip>

# Check routes
show ip route detail
show bgp evpn detail

# Check counters
show interfaces counters errors
show vxlan counters

# Check logs
show logging
show logging last 50

# Packet capture
bash tcpdump -i et11 -n port 179
bash tcpdump -i et11 -n port 4789
```

## Configuration Snippets

### Save Configuration
```bash
write memory
# or
copy running-config startup-config
```

### View Configuration
```bash
show running-config
show running-config | section bgp
show running-config | section vxlan
```

### Enable Configuration Mode
```bash
enable
configure terminal
```

## Testing Connectivity

### From Leaf Devices
```bash
# Ping loopbacks
ping 10.0.250.1
ping 10.0.255.13

# Ping in VRF
ping vrf gold 10.78.78.1

# Traceroute
traceroute 10.0.255.14
traceroute vrf gold 10.34.34.1
```

### From Host Containers
```bash
# Enter host container
docker exec -it clab-arista-evpn-fabric-host1 sh

# Test connectivity
ping 10.40.40.1
```

## Performance Monitoring

```bash
# Interface statistics
show interfaces ethernet 11 counters
show interfaces ethernet 11 counters rate

# BGP statistics
show bgp evpn summary
show bgp evpn route-type mac-ip | count

# System resources
show processes top
show version
```

## Useful Filters

```bash
# Grep examples
show bgp evpn summary | grep Estab
show interfaces status | include up
show running-config | section vxlan

# JSON output (for automation)
show bgp evpn summary | json
show interfaces status | json
```
